Question

Suppose two gases in a container have a total pressure of 1.20 atm. What is the pressure of Gas B if the partial pressure of Gas A is 0.75 atm?

Answer 1

Gas B= 0.45..... because all u need to do is subtract the total from the partial pressure of Gas A. Hope thats right and is able to help.

Answer 2

Answer: The partial pressure of Gas B is 0.45 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 = 1.20 atm

`p_A` = partial pressure of A =0.75 atm

`p_B` = partial pressure of B =?atm

putting in the values we get:

`1.20atm=0.75atm+p_B`

`p_B=0.45atm`

The partial pressure of Gas B is 0.45 atm.
