pv=nrt

The Attempt at a Solution

i solved it using the ideal gas equation and got a very large n value,after converting from mmHg to Pa? would that be the correct procedure?

quick few hints to doing this if your getting odd answers. a) temp needs to be converted to kelvin and b) the 1cm^3 needs to be correctly converted into m^3
