This converts atomic units to grams per mole, making the molar mass of hydrogen 1.007 grams per mole, of carbon 12.0107 grams per mole, of oxygen 15.9994 grams per mole, and of chlorine 35.453 grams per mole. We do not have enough moles of Cl2 to react all of P4, so Cl2 is the limiting reactant, but we are looking for the mass of the remaining unreacted P4, so we find the moles unreacted and convert that to grams: 0.3702mol P4 - 1.701molCl2(molP4/6molCl2) = 0.0867 mol P4 unreacted. 5.77g/32g = 0.1803 mol O2. 399.0215g 17. Thus, percentage of boron by weight in the compound = 0. To calculate the molar mass of the compound we need to look at the molar mass of each individual element that makes up the compound and how many atoms of each are present. The molar mass of PCl3 is 137.32 g/mol and may be useful. Correct answer: 91.68%. Mass of sample =0.24g. How much energy is required to decompose 765 g of PCl3, according to the reaction below?
