Question

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?

Answer 1

this question requires Dalton's law formula.

Total pressure= P1 + P2 +P3 +P4 ......etc..

so, all we have to do is add the pressure as long as they have the same units.

total pressure= 3.00 + 1.80 + 0.29 + 0.18 +0.10= 6.27 atm

Answer 2

it would actually be 5.37 atm.
