A eudiometer contains 65.0 ml sample of gas collected by the diplacement of water. The water levels inside and outside the eudiometer are the same. The atmospheric pressure is 92.5 kPa and the temperture is 23 degrees. What volume will the dry gas occupy at STP? The vapor pressure of water at 23 degrees is 2.8 kPa.

92.5kPa-2.8kPa= 89.7kPa

65.0 ml(89.7 kPa)/101.3 kPa

answer: 57.6 ml
