The relation of heat capacity with temperature for oxygen is given as Cp = 22.5 + 2.56 T, where Cp is in J/g.mol.˚C. What is the expression for heat capacity if the temperature is expressed in ˚R and Cp in Btu / lb.mole.˚R?

The relation of heat capacity with temperature for oxygen is given as Cp = 22.5 + 2.56 T, where Cp is in J/g.mol.˚C. What is the expression for heat capacity if the temperature is expressed in ˚R and Cp in Btu / lb.mole.˚R? Correct Answer -141.9 + 0.119 ˚R

˚C = (˚R – 460 – 32)/1.8 and 1 Btu = 1055 Jule.
