Nitrous oxide (N2O) is used as an anesthetic. The pressure on 2.50 L of N2O changes from 105kPa to 40.5 kPa. If the temperature does not change, what will the new volume be?

I know the Boyle's law is
P1 x V1 = P2 x V2

  • chemistry - ,

    You have the law correct, you are looking for V2

    V2=P1*V1/P2. Pressure was reduced by a factor of 2.5 (about) so volume ought to be increased by that same factor.
