A container of gas has a volume of 3.5 L and a pressure of 0.8 atm. Assuming the temperature remains constant, what volume of gas would result if the pressure was 0.5 atm?

A. 1.8 L

B. 5.6 L

C. 0.2 L

D. 2.2 L

5.6 L

Explanation:

We are given;

Initial volume, V1 = 3.5 L Initial pressure, P1 = 0.8 atm Final pressure, P2 = 0.5 atm

We are required to calculate the final volume;

According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at a constant temperature. That is; P α 1/V Mathematically, P=k/V At two different pressure and volume;

P1V1 = P2V2

In this case;

Rearranging the formula;

V2 = P1V1 : P2

= (0.8 atm * 3.5 L) : 0.5 atm

= 5.6 L

Therefore, the resulting volume is 5.6 L
