# (C) At 35C and 700 mm of hg pressure, a gas occupies a 500 ml volume. What will be its pressure when the temperature is 15$°$ C and the volume of the gas is 450 ml?

Dear Student,

From Ideal Gas Law,
We know that PV = nRT
So, nR = PV/T

Now,

Thus, the pressure will be 727 mmHg.

Hope it helps.

Regards
