Nitrogen gas, N2, is the only gas generated from the decomposition of an unknown substance. The reaction is run to completion and the gas produced was collected over water at a temperature of 298 K. The total pressure of the gas collected over the water is measured to be 2.25 atm. If the partial pressure of water at this temperature is 0.0351 atm then determine the partial pressure of N2 gas produced.
A. 1.80 atm
B. 2.21 atm
C. 2.28 atm
D. 3.10 atm
