how many kilograms of NH3 are needed to produce 2.90x10^5kg of (NH4)2SO4?
the balanced equation is:
2 NH3 + H2SO4 --> (NH4)2SO4
1. Convert 2.90x10^5kg of (NH4)2SO4 to kilogram•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.
