Expert Answer
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,
