Determine the theoretical yield of H2S (in moles) if 4.0 mol Al2S3 and 4.0 mol H2O are reacted according to the following balanced reaction. A possibly useful molar mass is Al2S3 = 150.17.I am having a little trouble with this one.nswers. Best Answer: You need 6 moles of H2O for every mole of Al2S3 but you have equal moles so the limiting factor with be the amount of H2O. From the equation 6 moles H2O gives 3 moles H2S So 4 moles H2O will give 2 moles H2S.
The molar mass of a substance is the molecular weight in grams. All you need to do is calculate the molecular weight and stick the unit g/mol after the number and that is the molar mass for the substance in question. Calculate the molar mass of Al(NO.(1 x 26.98) + (3 x 14.007) + (9 x 16.00) = 213.00 g/mol. 213.00 grams is the mass of one mole of aluminum nitrate.213.00 grams of aluminum nitrate contains 6.022 x 10 23 entities of Al(NO. Video: How to Calculate the Molar Mass. The World-Wide Web contains molecular weight calculators, both ones that are on-line and programs you can download.n one mole, there are 6.022 x 10 23 atoms. Here's another way: there are 6.022 x 10 23 atoms of carbon in 12 grams of carbon-12. Let's say that real clearly: one mole of ANYTHING contains 6.022 x 10 23 entities. The word entities is simply a generic word.
