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%.
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.
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.
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%.
To calculate the percent by mass of oxygen in Sb4O6, you need to determine the molar mass of the compound. The molar mass of Sb4O6 is 784.64 g/mol. Oxygen contributes 96 g/mol out of 784.64 g/mol, so the percent by mass of oxygen in Sb4O6 is (96/784.64) x 100% ≈ 12.2%.
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.
