Question

870 cc of moist hydrogen measured at 9 degree celsius and 659 mm pressure.find the volume of dry hydrogen at N.T.P .the vapur pressure of water at 9 degree celsius is 9 mm​

Answer 1

Answer:

Explanation:  Given: 870cc of moist hydrogen measured at 90C and 659 mm pressure.  

 

To Find: the volume of dry hydrogen at NTP

 

Solution:

By Using Dalton's Law;

Ptotal = Pdry hydrogen + Pwater

659  =  Pdry hydrogen +  9

Therefore, Pdry hydrogen = 650 mm

Let P1, V1 be the pressure and volume of the dry hydrogen respectively at temperatitr T1.

Let P2, V2 be the pressure and volume of the dry hydrogen respectively at temperatitr T2.

 

Let us calculate the volume V2 of dry hydrogen at NTP.

Using combined gas equation, we get,
