A mixture of ammonia and oxygen is prepared by combining 0.330 L of NH3 (measured at 0.790 atm and 22°C) with 0.210 L of O2 (measured at 0.820 atm and 48°C). How many milliliters of N2 (measured at 0.740 atm and 100. °C) could be formed if the following reaction occurs?

Question

A mixture of ammonia and oxygen is prepared by combining 0.330 L of NH3 (measured at 0.790 atm and 22°C) with 0.210 L of O2 (measured at 0.820 atm and 48°C). How many milliliters of N2 (measured at 0.740 atm and 100. °C) could be formed if the following reaction occurs?
4NH3(g) + 3O2(g) -> 2N2(g) + 6H2O(g)

Use PV =nRT and convert NH3 and O2 (each) to mols = n. Find the limiting regent Convert to mols N2 formed, the use PV = nRT and convert to mL at the conditions listed.
