1. 1. Convert 2.90x10^5kg of (NH4)2SO4 to kilogramâ€¢moles by dividing by 132.26 kg/kg.mol

2. Since 2 kg.moles of NH3 produces 1 kg.mole of (NH4)2SO4, multiply the answer to Step 1 by 2 to get kg.moles of NH3 needed.

3. multiply the previous answer by 17.09 kg/kg.mol of NH3 to get kgs of NH3 needed.
