Question

what will be the volume of a given mass of a gas at a pressure of 50 cm of Hg, if it occupies 260ml at a pressure of 98 cm of Hg keeping the temperature constant​

Answer 1

When temperature remains constant, then according to Boyle's law the volume of a fixed (or, given) mass of a dry gas is inversely proportional to the pressure of the gas.

In other words at constant temperature, the product of volume and pressure of the gas is a constant.

Here, let the initial pressure be P and initial volume be V.

Similarly, let the final pressure be p and final volume be v.

According to Boyle's law :

PV = pv

Or, 98 × 260 = 50 × v

Or, v = (98 × 260)/50

Or, v = 509.6 ml [ANSWER]

Answer 2

Answer:

509.6

Explanation:

I have solve

v1 we have to find

v2 = 260ml

p1 = 50 cm

p2 = 98 cm
