Q1)Fromt the stoichiometric equation given
3 moles of H2O reacts with Mg3N2 to form 2 moles of NH3
moles of H2O needed to form 4.72 moles of NH3 = 4.72 moles of NH3 x 3 moles of H2O / 2 moles of NH3
= 7.08 moles of H2O
Q2)
From the given equation
4 moles of NaF ( 4mol x 42g/mol) give one moles of SF4 (1 mol x 108g/mol)
Thus the mass of NaF required to give 422 g of SF4 = 422g SF4 x 4mol x 42g/mol NaF /1mol x 108g/mol
= 656.44 g
