The number of moles of nitrogen gas in each tire would be 1.595 moles
The ideal gas law is represented by the equation:
PV = nRT where P = pressure, V = volume, n = number of moles of gas, R = constant, and T = temperature.
In this case, P = 249 kpa, V = 15.6 L, R = 8.31, and T = 293 K (273 + 20).
n = PV/RT = 249 x 15.6/8.31 x 293 = 1.595 moles
