The specific heat of water is 4.18 j/(g⋅∘c). calculate the molar heat capacity of water. express your answer to three significan

iogann1982 [59]

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
