Question

Molar heat capacity of ethanol is $110.4J{K}^{-1}$ . Its specific heat capacity is

• A. 2.4
• B. 55.2
• C. 5.078
• D. 110.4

Answer 1

Answer: (A)

Specific heat capacity $=\frac{Molarheatcapacity}{molarmass}$ $=\frac{110.4J{K}^{-1}}{46}$ ( $\because$ Molar mass of ethanol = 46) $=2.4J{K}^{-1}mo{l}^{-1}$
