What is the volume of a sample of CO2 at STP that has a volume of 75.0mL at 30.0°C and 91kPa

60.7 ml is the volume of a sample of CO2 at STP that has a volume of 75.0mL at 30.0°C and 91kPa.

Explanation:

Data given:

V1 = 75 ml

T1 = 30 Degrees or 273.15 + 30 = 303.15 K

P1 = 91 KPa

V2  =?

P2 = 1 atm or 101.3 KPa

T2 = 273.15 K

At STP the pressure is 1 atm and the temperature is 273.15 K

applying Gas Law:

=

putting the values in the equation of Gas Law:

V2 =

V2 =

V2 = 60.7 ml

at STP the volume of carbon dioxide gas is 60.7 ml.
