Question

The volume of a gas at 740 mm pressure is 190 mL. What will be the volume at 370 mm pressure if the temp. remains constant?​

Answer 1

Explanation:

As per the Boyle's law, at constant temperature pressure is inversely proportional to volume.

P1V1 = P2V2

740 mm x 190 mL = 370 mm x V2

V2 = 740 mm x 190 mL/ 370 mm = 2 x 190 mL = 380 mL
