42 molecular mass and percent composition worksheet answers
molar mass percent composition ws2 (1).pdf - Physical... Determine the percent composition of each element in the following compounds. Express answers to twodecimal places.ex: SO2S = 1(32.066) = 32.066mass % S = mass S/mass SO2X 100;32.066/64.064 X 100 = 50.053% = 50.05%. O = 2(15.999) = 31.998mass % O = mass O/mass SO2X 100;31.998/64.064 X 100 = 49.946 % = 49.95%SO2= 32.066 + 31.998 = 64.06411. 5.4 Percent Composition, Empirical and Molecular Formulas The formula mass of ammonia is therefore (14.01 amu + 3.024 amu) = 17.03 amu, and its percent composition is: %N = 14.01amuN 17.03amuNH3 × 100% = 82.27% %H = 3.024amuN 17.03amuNH3 × 100% = 17.76% This same approach may be taken considering a pair of molecules, a dozen molecules, or a mole of molecules, etc.
