A volume of gas occupies 4L at 740 mmHg. What volume will the gas occupy at 337 mmHg?

Answer: 8.78 L

Explanation:

Given that,

Original volume of gas V1 = 4 L

Original pressure of gas P1 = 740 mmHg

New pressure of gas P2 = 337 mmHg

New volume of gas V2 = ?

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

P1V1 = P2V2

740 mmHg x 4L = 337 mmHg x V2

2960 mmHg L = 337 mmHg x V2

V2 = 2960 mmHg L / 337 mmHg

V2 = 8.78 L

Thus, the new volume of the gas is 8.78 Liters
