The work done by an ideal gas in an isothermal expansion from volume V1 to volume V2 is given by the formula: W = nRT ln(V2/V1).  Standard atmospheric pressure (1 atm) is 101.3 kPa.  If 1.0 L of He gas at room temperature (20 ºC) and 1.0 atm of pressure is compressed isothermally to a volume of 100 mL, how much work is done on the gas?
