Given: R=8.31451 J/(K*mol)

Two moles of helium gas initially at 187 K and 0.33 atm are compressed isothermally to 0.57 atm.
Find the final volume of the gas. Assume the helium to behave as an ideal gas. Answer in units of m^3.

I've tried this many many times and i keep getting 5.455 which is not right. can someone please help? Thanks
