Question

Four mole of hydrogen, two mole of helium and one mole of
water vapour form an ideal gas mixture. What is the molar
specific heat at constant pressure of mixture?
(a) 16/7 R
(b) 7/16 R
(c) R (d) 23/7 R

Answer 1

Explanation:

hey!!

ANSWER

CV for hydrogen =  25R

Cv for helium =  23R

VV for water vapour =  26R=3R

∴ (CV)mix =  4+2+14× 25R+2× 23R+1×3R =  716R

∴ CP = CV+R

CP =  716R+R

Or, CP =  723R
