I'm looking for a piece of glassware from France. 1. Which compound has the highest percent composition by mass of strontium? D is your answer The answer is (3) SrO.The number of Sr is the same so if the compound has the smallest gram formula mass, it has the highest percent composition by mass of strontium. 3/2. Ascorbic acid (vitamin C) contains only C, H, and O. C 39.97% H 13.41% N 46.62% By calculating for the mass percent of oxygen in each of the choices, we find that choice c. {eq}Mg(NO_3)_2 {/eq} has the highest mass percent of oxygen. Since the sample contains C, H, and O, then the remaining. a) CaSO 4 is calcium sulfate b) NaCO 3 is sodium carbonate c) K 2 S is potassium sulfide d) Mg(OH) 2 is magnesium hydroxide e) BaCl 2 is barium chloride. A) MnO B) Mn2O3 C) Mn3O2 D) MnO2 E) none of the above. = 12.6% hydrogen by mass. Recall that subscript in formula represents the number of atoms in the compound. 100% - 40.9% - … A compound with the following mass percent composition has a molar mass of 60.10 g/mol. 91.9% B. ... which compound has the highest percent composition by mass of strontium. However, each molecule has only 1 carbon in which simplifies this a lot. Most fertilizers consist of nitrogen-containing compounds such as NH3, CO(NH2)2, NH4NO3, and (NH4)2SO4. Calculate the mass percent composition of carbon in each carbon-containing compound:c. C2H2. i think CH4 . Mass percent tells you the percentage of each element that makes up a chemical compound. So the answer is (3). Y is known to be 60% X by mass. H2O2. A compound has the following percent (by mass) composition: 87.2% Ti (thallium, atomic number = 81), 2.6% C and 10.2% oxygen. The mass percent of FeO originally in the mixture was: A. 12.01 amu. Now, we need to get the moles of each element in the compound. 12.01 amu. The number of moles in 12.0 g of C 2 6. Solution for Which one of the following has the smallest mass percent of F in the compound? Another way to ask the question is: which weighs least: 2 O atoms, 4 H atoms, 1 N atom or 1 O atom? Trump to return to White House early from Florida, Dancer, 'Electric Boogaloo' star Quiñones dead at 65, Pet food recalled after at least 28 dogs die: FDA, Report: Player from '85 Bears SB team arrested for murder, Dawn Wells, Mary Ann on 'Gilligan's Island,' dies at 82, NFL coach explains how decision to cut QB went down, Small Colorado town confronts coronavirus variant, Strong early turnout in Ga. runoffs puts GOP on edge, The year in Meghan Markle: A royal exit, activism and loss, Man in hospital with COVID-19 after GOP holiday party. Calculate the empirical formula of the compound… Calculate the mass percent composition of nitrogen in each of the fertilizers named in this problem. (a) CH 4 (b) CHCl 3 (c) C 12 H 10 O 6 (d) CH 3 CH 2 CH 2 CH 2 CH 3. Get your answers by asking now. Q. B) Srl2 45) A) SrO C) SrCh D) SrS 46) Which compound has the smallest percent composition by mass ofchlorine? Calculate the percent Y by mass of the compound X Y.. H O (molar mass = 46.1 g/mol) is calculated as follows. Answer a. Still have questions? Recall that mass percent is given by: % mass = mass X Total mass x 100. In the calculations below, I have rounded the masses to whole numbers. Plants use the nitrogen content in these compounds for protein synthesis. What are the formula and name of the compound? 20. 71.4% C. 28.6% D. 49.3% E. none of these 43. Divide the mass of hydrogen in each compound by the molar mass of the compound and multiply by 100. How to solve: Which compound contains the highest percent by mass of hydrogen? Here, number of carbon atom is same in each compound. 2.016/32.0 X 100 = 6.3%. The number of Sr is the same so if the compound has the smallest gram formula mass, it has the highest percent composition by mass of strontium. asked Oct 11 in Other by manish56 (-13,778 points) 0 votes. High temperature high pressure treatment of a heavy metal. https://quizlet.com/55801470/chemistry-1122-midterm-ii-flash-cards ... Our tutors have indicated that to solve this problem you will need to apply the Mass Percent Formula concept. Get your answers by asking now. 1. Answer d. 60.05 amu. Trump to return to White House early from Florida, Dancer, 'Electric Boogaloo' star Quiñones dead at 65, Pet food recalled after at least 28 dogs die: FDA, Report: Player from '85 Bears SB team arrested for murder, Dawn Wells, Mary Ann on 'Gilligan's Island,' dies at 82, NFL coach explains how decision to cut QB went down, Small Colorado town confronts coronavirus variant, Strong early turnout in Ga. runoffs puts GOP on edge, The year in Meghan Markle: A royal exit, activism and loss, Man in hospital with COVID-19 after GOP holiday party. Which fertilizer has the highest nitrogen content? since it is just Mn and O we need the highest ration. since it is just Mn and O we need the highest ration. 2/3. (H = 1; C = 12; O = 16). b. H_2O. grendeldekt and 54 others learned from this answer The answer is (3). Furaneol has three elements in differing ratios, six carbon to eight hydrogen to three oxygen. Which compound contains the highest percent by mass of hydrogen 1 answer below » Which compound contains the highest percent by mass of hydrogen? What is the empirical formula of the compound? Which compound/formula name combination is INCORRECT? The correct answer would be CH4 because 4H weighs less than 1N which weighs less than 1O which weighs less than 2O, and so CH4 has the highest mass percent of Carbon. Which of the following has the highest mass percent of hydrogen? Which compound has the highest mass percent C? 3. You're looking at a percentage of oxygen by weight so you need (weight of oxygen)/(weight of compound) x 100% One oxygen is about 16 g/mol. CO. What is the mass percent N in C2H8N2? Which of the following compounds has the highest mass percent of "O"? you have the same 2.016 grams hydrogen here, but you have 32.0 grams oxygen in this molecule. Compound X 2 2 2 2. C3H6O. 46.6 % N. A compound is 62.03 % C, 10.41 % H, and 27.55 % O by mass. You can view video lessons to learn Mass Percent Formula. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). It is simply calculated using a basic formula dividing the mass of the element (or solute) by the mass of the compound (or solution). Find the Empirical and Molecular formula of the compound. Finding the mass percent requires the molar mass of the elements in the compound in grams/mole or the number of grams used to make a solution.
