Question

The ratio of the initial to the final pressure of a given mass of gas is 1:1.5. Calculate the final volume of the gas if the initial volume was 300cm^3 at the same temperature. ​

Answer 1

According to Boyle's Law, the pressure and volume of a given amount of gas at constant temperature are inversely proportional. The final volume can be calculated by multiplying the initial volume by the ratio of the final pressure to the initial pressure.

Step-by-step explanation:

According to Boyle's Law, the pressure and volume of a given amount of gas at constant temperature are inversely proportional. This means that as the pressure increases, the volume decreases, and vice versa.

In this question, the ratio of the initial to final pressure is given as 1:1.5. Since the initial pressure is equal to the final pressure (1:1), the final volume must be 1.5 times the initial volume.

Given that the initial volume is 300 cm3, the final volume can be calculated as 300 cm3 * 1.5 = 450 cm3.

Answer 2

Step-by-step explanation:

Ratio of volume 1:1.5 = 300/v

1/1.5 = 300/v

Cross multiply

v = 1.5 × 300

V = 450cm^3
