Question

If two gases are present in a container, the total pressure in the container is equal to

Answer 1

(A) the sum of the pressures that are exerted by each of the two gases.

Step-by-step explanation:

Answer 2

Answer: sum of the pressure of the two gases present.

Step-by-step explanation:

According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.

`p_(total)=p_A+p_B`

For example if there are there are two gases hydrogen and oxygen with individual pressure of 30 and 20 atm each. Then the total pressure in the container will be:

`p_(total)=p_(H_2)+p_(O_2)`

Thus
`p_{total|=30atm+20atm`

`p_(total)=50atm`

Thus if two gases are present in a container, the total pressure in the container is equal to sum of the pressure of the two gases present.
