A mixture of helium of neon gases is collected over water at `28.0^(@)C` and 745 mmHg. If the partial pressure of helium is 368 mmHg, what is the partial pressure of neon?

A

348.7 mmHg

B

377 mmHg

C

384.7 mmHg

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
a
(a) `P_(T)=P_(He)+P_(Ne)+V.PH_(2)O`
`745=368+P_(Ne)+28.3`
`P_(Ne)=348.7 mm " of " Hg`
