What is percent by mass of carbon in acetone C3H6O?
To calculate the percent by mass of carbon in acetone (C3H6O), first calculate the molar mass of carbon in acetone: 3(C) = 3(12.01 g/mol) = 36.03 g/mol. Then calculate the molar mass of acetone: (3(12.01 g/mol) + 6(1.01 g/mol) + 16.00 g/mol = 58.08 g/mol. Finally, divide the molar mass of carbon by the molar mass of acetone and multiply by 100 to get the percent by mass of carbon in acetone: (36.03 g/mol / 58.08 g/mol) x 100 ≈ 62.07%.
Calculate the mass in grams of 2.60 mol of potassium chloride (KCl).?
You can calculate the molar mass of potassium chloride (KCl) by adding the atomic masses of potassium (K = 39.10 g/mol) and chlorine (Cl = 35.45 g/mol). The molar mass of KCl is 74.55 g/mol. To find the mass of 2.60 mol of KCl, multiply the molar mass by the number of moles: 2.60 mol * 74.55 g/mol = 193.53 grams.
What is the mass of 0.0435 mol zinc chloride?
To find the mass of zinc chloride (ZnCl2) in 0.0435 mol, you need to calculate the molar mass of ZnCl2, which is 65.38 g/mol. Multiplying 0.0435 mol by the molar mass gives a mass of approximately 2.84 g.
What is the mass percent of oxygen in phenylalanine?
The molecular formula of phenylalanine is C9H11NO2. To calculate the mass percent of oxygen in phenylalanine, we first need to calculate the molar mass of the compound. This molar mass is found to be 165.19 g/mol. The mass percent of oxygen in phenylalanine is then found to be (32.00 g/mol / 165.19 g/mol) * 100 ≈ 19.38%.
What is the percent by mass of oxygen in sb4o6?
The properly written formula is Sb4O6, showing that each unit contains 4 antimony atoms and 6 oxygen atoms. The gram atomic mass of oxygen is 15.9994 and that of antimony is 121.75. Therefore, the percent by mass of oxygen is 100{(6)(15.994)/[(4)(121.75) + (6)(15.994)} or 16.466, to the justified number of significant digits. (The integers 4 and 6 are exact).
How do you calculate 0.00844 mol in grams of NiSO4?
To calculate the mass of 0.00844 mol of NiSO4, you need to know the molar mass of NiSO4. It is 154.756 g/mol. So, multiply the number of moles (0.00844) by the molar mass (154.756 g/mol) to get the mass in grams, which is approximately 1.30 grams of NiSO4.
