Question

How to calculate equivalent mass of calcium phosphate?

Answer 1

the chemical formula of the given compound is

Ca3(PO4)2

now calculate the change in the electrons

the equivalent weight of the compound is given by weight of the compound divided by the n-factor( here electrons)

so

310/2 is the answer

Answer 2

Equivalent mass of calcium phosphate is 51.697.

Explanation:

Equivalent mass is the ratio of molecular mass to the n factor.

Calcium phosphate $(Ca_3(PO_4)_2)$ is a salt and the equivalent mass of a salt is calculated by using the formula:

[tex]\text{Equivalent mass}=\frac{\text{Molar mass of salt}}{\text{Charge on ion }} [/tex]

Molar mass of salt = 310.18 g/mol

Charge on ion = 6

[tex]\text{Equivalent mass}=\frac{310.18gmol}{6} =51.697[/tex]

Thus equivalent mass of calcium phosphate is 51.697.
