What volume would 3.25 moles of CO2 occupy at STP?

V

=

1.18

L

Explanation:

In order to solve this problem we would use the Ideal Gas Law formula  

P

V

=

n

R

T

P

Explanation:

the volume of fluid displaced would equal the volume of the gas. use a gas syringe - this is a laboratory instrument that can be used to withdraw a certain volume of gas from a closed system or to measure the volume of gas from a chemical reaction.
