For this reaction: 4NO2 (g) + O2 (g) + 2H2O (l) → 4HNO3 (aq). How much HNO3, in grams, is produced when 1500 g of NO2 reacts?

Answer 1

1. We need to determine how many moles of NO₂ react (using its molar mass). This is because a reaction is based on molar ratios.

NO₂ Molar Mass: (46.01 g / mol)

NO₂ Moles: 1500 g * (1 mol / 46.01 g) = 32.60 mol NO₂

1. We need to determine how many moles of HNO₃ are produced from this much NO₂ based on the given chemical reaction.

From reaction:

4 mol NO₂ → 4 mol HNO₃

HNO₃ Moles: 32.60 mol NO₂ * (4 mol HNO₃ / 4 mol NO₂) = 32.60 mol HNO₃

1. We can determine how many grams of HNO₃ are produced (using its molar mass)

HNO₃ Molar Mass: (63.01 g / mol)

HNO₃ Grams: 32.60 mol * (63.01 g / 1 mol) = 2054.13 grams HNO₃
