answer and explanation.
to determine the mass of hydrogen sulfide needed we must first determine the number of mols using the ideal gas equation which is
PV = nRT
we can the rearrange this equation to make n subject of the formula like so:
n = PV/RT
= (1809.7 x 50)/ (8.314 x444)
= 24. 5 mols
using the number of mols we can then determine the mass needed using te following equation
m = nM
m = (24.5 mol x 34.1g/mol)
= 835.9 grams
