1. Convert degrees C to degrees K.
K = C + 273
Convert torrs to atm.
atm = torrs / 760

Substitute in PV = nRT and solve for V

4. Must think of this as a ratio. The conditions are all the same. If 3.21mol occupies 56.2L then 5.29mol occupies X liters.

3.21mol/56.2L=5.29mol/X

Cross multiply and divide.

Ans= 92.6L
