    What is the molar heat capacity of liquid water?
    The specific heat capacity of water is c= 4.184 J• g-1•C-1
    1 mole of water is 18 grams. Then the molar heat capacity is

    What is the heat capacity of 160 of liquid water?
    Is this 160 moles or 160 grams of water?
    If 160 moles of water, then the heat capacity is

    If it is 160 grams of water, the heat capacity is

    How many kJ of heat are needed to raise the temperature of 15.00g of liquid water from 24.8 C to 46.3 C?
    The temperature change is
    Then the heat needed is

    1.35 kJ heat is required.
