A container holds 500. mL of CO2 at 20 degrees C and 742 torr. What will be the volume of the CO2 if the pressure is increased to 795 torr?

Solutions

Expert Solution

Volume of CO2 =V1 = 500 mL

=

=0.500 L

Temperature = 20 oC

Pressure = P1 =742 torr = 0.976 atm

=0.976 atm

Pressure of CO2 =P2 = 759 torr =

= 0.999 atm

We have to use Boyle's law assuming CO2 is a ideal gas

Formula for Boyle's law

P1V1 = P2V2

0.976 atm (0.500 L) = 0.999 atm (V2)

0.488 = 0.999 *V2

Divide both sides by 0.999

0.488 L = V2

New volume of CO2 = V2 = 488 mL
