Question

You have 2 1L containers each equipped w a pressure gauge. One contains F₂ and one contains Cl_2. Each container holds 7g of gas. How could you find out which gas is which without opening the container using ideal gas law?

Answer 1

As they equipped with pressure gauge so we can measure pressure.

Now, here volume and temperature is same for both only no. Of moles are different.

no. Of moles is directly proportional to pressure so which has high pressure will havs more no. Of moles.

So we calculate mole here directly we can see that molar mass of F2 is less as compare to Cl2 so,

Moles of F2 > moles of Cl2 ( beacuse both have same mass)

So pressure of container in which F2 is present is high as compare to the Cl2.
