The specific heat of water is 4.18 j / (g⋅∘c). calculate the molar heat capacity of water. express your answer to three significant figures and include the appropriate units.

Specific heat capacity of any substance comes with the unit : J / (g*degree C)

for molar capacity, change gram - > moles unit (J / moles * degree C)

4.18 J / mol - degree C

H = 1.01 g * 2 = 2.02 g

O = 16 g

2.02 + 16 = 18.02 g

Now : - 4.18 J / mol - degree C) * 18.02 / 1 mole H2O

molar heat = 75.3 J / mol - degree C
