Explanation / Answer

Specific heat capacity of water/ice = 2.06 J/g C

Molar specific heat of the substance = (molar mass of substance) * (Specific heat capacity of water/ice)

=> 18.01 g/mol * 2.06 J/g C

=> 37.1006 J/mol C

Since the significant digits are 4 in 18.01 and 3 in 2.06

Hence there will be three significant digits in molar specific heat of the substance, hence the answer is 37.1 J/mol C

Correct answer is Option A
