Molecular mass of Calcium sulphate is CaSO 4 = ( Atomic mass of Calcium ) x 1 + (Atomic mass of Sulphur) x 1 + (Atomic mass of Oxygen) x 4 = ( 40 x 1

Example 1: Calculate the weight of one mole of CaSO4 7H2O.? = 262.25 g. dissolved and diluted to the corresponding fraction or multiple of a liter. Molar is ...

Equivalent weight of sulphate redical =(32+16xx4)/(2)=48.

The equivalent weight of any element can be calculated using the formula; Equivalent weight = Molecular weight X Where, X = valence factor.

The atomic weight of calcium is nearly 40 gm/mol. Thus, the equivalent weight of calcium metal is 20. Therefore, option (D) is correct. Note: Do note that the ...
