Question

A 200 of gas is contained in a vessel under a pressure of 850 mmHg. What would be the new volume of the gas if the pressure is change to 1000mmHg? Assume that the temperature remains constant.

Answer 1

Answer: 170

Explanation:

Initial volume of gas V1 = 200 (liters, ml, dm3 or cm3)

Initial pressure of gas = 850 mmHg

New volume of gas V2 = ?

New pressure of gas P2 = 1000mmHg

Since pressure and volume are involved while temperature is constant, apply the formula for Boyle's law

P1V1 = P2V2

850 mmHg x 200 = 1000 mmHg x V2

170000 = 1000V2

Divide both sides by 1000

170000/1000 = 1000V2/1000

170 = V2

Thus, the new volume of the gas is 170 (liters, ml, dm3 or cm3)
