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

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

b) twice the sum of the pressures that are exerted by the individual gases.

c) the sum of the pressures that each gas would exert if they occupied twice the volume.

d) the sum of the pressures that each gas would exert if they occupied half the volume.

The correct answer is option A) the sum of the pressures that are exerted by each of the two gases.

The pressure exerted by a mixture of gases in the container is equal to the sum of the pressure exerted by the each gas present in the container.

According to the Raoult's Law, the total pressure of the gas is equal to the partial pressure of the each gas present in the container. In case, there are two gases present in the container, then total pressure would be:

where P = total pressure.

partial pressure of gas 1.

partial pressure of gas 2.

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.
