Question

A volume of 780mL CO2 gas was produced at 37 degrees celcius at 1atm. What is the volume of gas if temperature measured was 22 degrees celcius and presure was 675mm/Hg

Answer 1

The volume decrease due to temperature is:

(22+273) / (37+273) = 295 / 310

and the volume increase due to the change in pressure is:

760 mmHg / 675 mmHg

780 mL * (295/310) * (760/675) = 835.7 mL
