Question

The partial pressures of the gases in a mixture are 0.00461 atm O2, 1.78 atm

N2, and 0.975 atm Ar. What is the total pressure of the mixture?

Answer 1

Answer: The total pressure of the mixture is 2.76 atm

Step-by-step explanation:

According to Dalton's law, the total pressure is the sum of individual pressures.

`p_(total)=p_A+p_B+p_C...`

Given :
`p_(total)` =total pressure of gases = ?

`p_(O_2)` = partial pressure of oxygen = 0.00461 atm

`p_(N_2)` = partial pressure of nitrogen = 1.78 atm

`p_(Ar)` = partial pressure of argon = 0.975 atm

putting in the values we get:

`p_(total)=0.00461atm+1.78atm+0.975atm`

`p_(total)=2.76atm`

Thus the total pressure of the mixture is 2.76 atm
