Answer:

The molar heat capacity of water 75.24 J/mol °C.

Explanation:

Specific heat is defined as amount of energy required to raise by the temperature of 1 g of substance by 1 degree Celsius.

Molar eat capacity as amount of energy required to raise by the temperature of 1 mole of substance by 1 degree Celsius.

Specific heat and molar heat capacities can be written:

Molar heat capacity = Specific heat × Molar mass of the substance

Specific heat of water = 4.18 J/g °C

Molar mass of water = 18 g/mol

Molar heat capacity of the water :

[tex] 4.18 J/g ^oC\times 18 g/mol= 75.24 J /mol^oC[/tex]

The molar heat capacity of water 75.24 J/mol °C.

The molar heat capacity of water that has a specific heat of 4.18 J/g°c is 75.24J/mol°C.

MOLAR HEAT CAPACITY:

  • The molar heat capacity of water can be calculated by multiplying the specific heat of the water by its molar mass. That is;

  • Molar heat capacity = specific heat × molar mass

  • Molar mass of H2O = 1(2) + 16 = 18g/mol

  • Molar heat capacity = 18g/mol × 4.18 J/g°c

  • Molar heat capacity of water = 75.24J/mol

  • Therefore, molar heat capacity of water that has a specific heat of 4.18 J/g°c is 75.24J/mol°C.
