Question

A mixture of two gases has a total pressure of 5.7 atm . If one gas has a partial pressure of 4.1 atm , what if the partial pressure of the other gas ?

Answer 1

if the two gases has a total pressure of 5.7 atm and one of the gases has a partial pressure of 4.1 the the other one has the pressure of 1.6

Answer 2

1.6 atm

Step-by-step explanation:

We are given that total pressure of mixture of two gases=5.7 atm

Partial pressure of one gas=4.1 atm

We have to find the partial pressure of other branch.

We know that Dalton;s law of partial pressure

It states that pressure exerted by mixture of gases is equal to sum of partial pressure exerted by gases in mixture.

Let x bet the pressure exert by other gas

Apply this law

Total pressure=4.1+x

`5.7=4.1+x`

`x=5.7-4.1=1.6`

Hence, the partial pressure of other gas=1.6 atm.
