1. What is the volume
occupied by 20.4 liters of
CO2 at 1200 Torr when it is
at STP

Explanation:

From your question you’ll have to assumethat the temperature is constant,since you do not have an initial temperature.

If thats the case thrn you can use;

P1V1=P2V2 to calculate the second volume.

P1=1200 torr

P2=760 torr

V1 = 20.4L

relative humidity is a measure of the amount of moisture in the air relative to the total amount of moisture the air can hold.
