Question

An argon gas occupies 56.2 L at 760 torr. If the volume of gas dereases to 1/4 of the original volume ,calculate its final pressure

Answer 1

Answer:

3040 torr

Explanation:

Applying,

PV = P'V'..................... Equation 1

Where P = Initial Pressure, V = Initial volume, P' = Final pressure, V' = Final volume.

Make P' the subject of the equation

P' = PV/V'................. Equation 2

From the question,

Given: P = 760 torr, V = 56.2 L, V' = 56.2/4 = 14.05 L

Substitute these values into equation 2

P' = (56.2×760)/14.05

P' = 3040 torr
