The specific heat of water is 4.18 j/(g⋅∘ c. calculate the molar heat capacity of water.

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 :

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

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

c.
