NH4NO3 (aq) + (heat) --> 2 H20 (l) + N2 (g)
Calculate the mass in grams of ammonium nitrate that must be used to produce 1.50 L of nitrogen gas collected over water at 30°C and 748 torr. At 30°C, PH20 = 31.8 mmHg. Find the moles of nitrogen gas.

Use PV = nRT to solve for n = moles N2 needed at STP.
For P, use (748-31.8/760) and don't forget T must be in kelvin.
Then use this example to solve for grams NH4NO3.
