what volume of ammonia gas, measured at 647.5 mmHg and 36.1C is required to produce 6.53 g of ammonium sulfate according to the following. 2NH3+H2SO4-(NH4)2SO4

1 answer

mols (NH4)2SO4 you want = grams/molar mass = ?
Convert mols (NH4)2SO4 to mols NH3 using the coefficients in the balanced equation.
Then convert mols NH3 volume (in L) using PV = nRT.
