FORMULA: % Hydration =molar mass of water(g) / molar mass of compound
*100

in green vitriol  

Explanation:

Atomic mass of Fe = 56 g/mol

Atomic mass of S = 32 g/mol

Atomic mass of O = 4 g/mol

Atomic mass of H = 1 g/mol

Molar Mass of  

Molar Mass of

% hydration  

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
