The pressure of the gas is 1
atm. We must convert the pressure from atm to kilopascals.
1 atm = 101.3kPa

Place the values of each variable in the formula and solve for the volume
V = (0.1 X 8.31 X 298 ) / 101.3 = 2.44 litres

A 4.4 gram pure sample of dry ice(carbon dioxide) was placed in a syringe as shown on the right. The plunger was allowed to expand under atmospheric pressure. What volume did the gas finally occupy if the temperature of the gas was 25oC? Atomic
mass of C =12, O =16
