How to solve for molar heat capacity
WebOct 10, 2024 · Molar heat capacity is expressed in units of J/K/mol or J/mol·K, where J is joules, K is Kelvin, and m is number of moles. The value assumes no phase changes occur. You'll typically start out with the value … WebFirst, we calculate (or find) the molar weight of methanol: 1*12.01g/mol C + 4*1.008g/mol H + 1*16.00g/mol O = 32.04 g/mol CH3OH Then, the specific heat capacity of methanol is: cp = 81.8 J/ (molK) / 32.04 g/mol = 2.53 J/ (g K) Converting between commonly used Units 1 Btu/lbmoF = 4186.8 J/kg K = 1 kcal/kgoC
