c) 295.27 amu. d) 190.37 amu. e) 569.93 amu. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Answer e) Each of the choices above would produce the same amount of product. Each will produce 2 mol of H2O: For choice a, H2 is limiting; 2.0 mol H2 will produce 2.0 mol H2O.
Dividing each result by the lowest number of moles (which may be for either P or S) and finding the lowest whole-number ratio of P and S gives us the empirical formula. To obtain the molecular formula, we compare the molar mass of the empirical formula to that given for the molecular formula (444.56 g/mol).
Correction: 2 moles of H2 reacts with one mole of O2 to produce 2 moles of H2O. Balanced equation 2H₂ + O₂ → 2H₂O Calculate moles of H₂O in 54 g. n = m/M; where n = moles, m = mass (g), and M = molar mass (g/mol). m(H₂O) = 54 g H₂O M(H₂O) = (2×1 g...
