Question

What volume of ammonia gas, measured at 489.9 mmHg and 37.4oC, is required to produce 8.41 g of ammonium sulfate according to the following balanced chemical equation? 2NH3(g) + H2SO4(aq) (NH4)2SO4(s) What volume of ammonia gas, measured at 489.9 mmHg and 37.4oC, is required to produce 8.41 g of ammonium sulfate according to the following balanced chemical equation? 2NH3(g) + H2SO4(aq) (NH4)2SO4(s) What volume of ammonia gas, measured at 489.9 mmHg and 37.4oC, is required to produce 8.41 g of ammonium sulfate according to the following balanced chemical equation? 2NH3(g) + H2SO4(aq) (NH4)2SO4(s)

Explanation / Answer

Number of mols of NH 3 required to produce the given amount of ammonium sulfate

= (8.41 g)(1 mol / 132.14 g/mol) (1 (NH4)2SO4 / 2 NH3) = 0.0318 mol NH3

Therefore, V = nRT /P = (0.0318 mol)(0.0821 L.atm/mol.K)(37.4+273)K *760 / 489.9 = 1.26 L
