Question

Based on the information below, how many grams of ammonium perchlorate, NH4ClO4, can be found from these reactants in an excess of water?

Answer 1

First find the mass of NH3 and HCl (multiply density by volume). You can then use the mass to find the moles (by dividing each compound by its molar mass).

After that it becomes a limiting reagent problem. Find the limiting reagent, then use it to find the moles of NH4ClO4 produced. Multiply by the molar mass to get the mass and you'll have your answer!
