What is the pressure of one mole of an ideal gas at 273 K and in a volume of 1m3
This question uses the ideal gas equation. pV = nRT where the temperature is in Kelvin, the pressure in pascals and the volume in m3. To obtain the number of moles the equation is rearranged to give p = nRT/V. The next step is then to use the value of the ideal gas constant R = 8.314 and substitute the values given in to obtain a value for the pressure.
