A sample of oxygen (O2) was collected by water displacement at 23°C when the ambient pressure was 753 torr. The volume of the gas over water was 600 mL. If the water vapour could be removed from the gas sample, what volume (in mL) would the dry O2 gas occupy under the same conditions?

The vapour pressure of water at 23°C is 21.0 torr.
