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? Use P subscript T equals P subscript 1 plus P subscript 2 plus P subscript 3 plus ellipsis plus P subscript n..
5.08 atm
5.19 atm
5.27 atm
5.37 atm

The total pressure that is exerted by the gases : 5.37 atm

Given

Partial pressure of the gas

Required

The total pressure

Solution

Dalton's law of partial pressures stated that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases  

Can be formulated:  

P₁=3 atm

P₂=1.8 atm

P₃=0.29 atm

P₄=0.18 atm

P₅=0.1 atm

P total :

Pt = 3 + 1.8 + 0.29 + 0.18 + 0.1

Pt = 5.37 atm

the answer is symmetrical : )
