Answer 1

Hey mate here is your answer

Question:

A certain gas has p c = 0.913 and v c = 0.653 kj/kg k. Find the molecular weight and the gas constant r of the gas

Answer:

Cp=0.913kj/kg.k

Cv=0.653kj/kg.k

find M?

specfic gas constant R

Gas contant (R) =Cp-Cv

                        =0.913-0.653

    (R)               = 0.26kj/kg.k

     R=Ru/M→0.26=8.314/M

(  M)=8.314/0.20→31.98kg/kg.mol

Hope this will help
