Homework Statement
When the volume of a gas is 2.81 L, the pressure is 740 Torr and the temperature is 20oC, how many moles of gas is there?
Homework Equations
PV=nRT
The Attempt at a Solution
740 Torr = 740*133.3 = 98.6*10^3 Pa
Temperature in Kelvin: 293 K
n = PV/RT = (98.6*10^3 * 2.81) / (8.3145*293) = 114 moles
The corret answer is 0.114 moles. Does this mean that when using the ideal gas law, the pressure should be in kPa?
