Five gases combined in a gas cylinder have the following partial pressures: 3.00 atm (N2), 1.80 atm (O2), 0.29 atm (Ar), 0.18 atm (He), and 0.10 atm (H). What is the total pressure that is exerted by the gases?

A5.08 atm
B5.19 atm
C5.27 atm
D5.37 atm

Verified Answer :

This can be solved using Dalton's Law of Partial
pressures. This law states that the total pressure exerted by a gas mixture is
equal to the sum of the partial pressure of each gas in the mixture as if it
exist alone in a container. In order to solve, we need the partial pressures of
the gases given. Calculations are as follows:


P = P1 + P2 + P3 + P4 + P5
P = 
3.00 atm + 1.80 atm + 0.29 atm + 0.18 atm + and 0.10 atm
P = 5.37 atm

using daltons law it would equal 5.37 atm.
