Ammonium nitrite, NH4NO2, decomposes upon heating to form N2 gas: NH4NO2 (s) → N2 (g) + 2H2O (l)
When a sample of NH4NO2 (Molar mass = 64.02 g per mol) is decomposed in a test tube, 511 cm3 of N2 gas is collected over water at 26 ºC. The total pressure is 99.3 kPa and the water vapor pressure at 26 ºC is 3.33kPa.
How many grams of NH4NO2 are decomposed?
Give your answer correct to three significant figures.
R = 0.08205 L·atm/mol·K
