A 0.109g sample of a pure gaseous compound occupies 112ml at 100degrees and 750torr: what is the molecular weight of the compound. ANS=(30.2g,mol). Please I need the solution

Answer 1

We try not to do your work for you. Use PV = nRT and solve for n = number of mols.
Then n = grams/molar mass. You know grams and n, solve for molar mass.

Answer 2

30.2 g/mL
