Question

A sample of oxygen gas occupies a volume of 335 mL at 704 torr pressure. What volume will it occupy at 852 torr pressure?


(round to two decimal places)

Answer 1

Answer:

276.81cm³

Explanation:

V1 = 335mL

P1 = 704 torr

V2 = ?

P2 = 852 torr.

V1 = 335cm³ (1mL = 1cm³)

From Boyle's law,

The volume of fixed mass of gas is inversely proportional to its pressure provided the temperature remains constant.

P1 * V1 = P2 * V2

V2 = (P1 * V1) / P2

V2 = (704 * 335) / 852

V2 = 235840 / 852

V2 =276.807

V2 = 276.81 cm³
