The fertilizer ammonium sulfate, (nh4)2so4, is prepared by the reaction between ammonia (nh3) and sulfuric acid: 2nh3(g) + h2so4(aq) ? (nh4)2so4(aq) how many kilograms of nh3 are needed to produce 3.60 × 105 kg of (nh4)2so4?

The chemical reaction would be:

2nh3(g) + h2so4(aq) = (nh4)2so4(aq)

To determine the ammonia needed, we use the given amount of the product to be produced and use the chemical equation to relate the substances. We do as follows:

3.60 × 105 kg (nh4)2so4 ( 1 kmol / 132.14 kg ) ( 2 kmol NH3 / 1 kmol (nh4)2so4 ) (17.04 kg / 1 kmol ) = 92846.98 kg NH3 needed
