Calculate the approximate pressure of a 2.0 mol sample of gas at 10.0 ºC and a volume of 15 L?
10.0oC = 273 + 10 = 283 K
According to the ideal gas law,
p=nRTV=2.0mol×8.314J/mol⋅K×283K15L=310kPap=\frac{nRT}{V}=\frac{2.0mol\times8.314J/mol\cdot{K}\times283K}{15L}=310kPap=VnRT=15L2.0mol×8.314J/mol⋅K×283K=310kPa
Answer: 310 kPa
