How many liters of CO2 gas are contained in a 3.16 liters of a gas mixture which is 8.1% (v/v) CO2?
They never gave us the formula or a process to figure this out in class. Will you please help?

The usual formula for %v/v is (volume gas/total volume)*100 = %.
(x L CO2/3.16L)*100 = 8.1%
Solve for x L CO2.
(x L CO2/3.16L)*100 = 8.1%
Solve for x L CO2.

Would the answer be .25596?
8.1/100= .081
.081*3.16= .25596
8.1/100= .081
.081*3.16= .25596
