Equal volume of two gases which do not r...

Equal volume of two gases which do not react together are enclosed in separate vessels. Their pressures are 10mm and 400mm respectively. If the two vessels are joined together, then what will be the pressure of the resulting mixture (temperature remaining constant)?

A

125 mm

B

500 mm

C

1000 mm

D

250 mm

Text Solution

Verified by Experts

The correct Answer is:
D
When two vessels are joined together, volume will be doubled hence effective pressure will be halved.
`P=(P_(1)+P_(2))/(2)=(100+400)/(2)=250` mmHg
