The mass percentage of nickel in nickel phosphate is 48.1%.

Percentage by mass of nickel in nickel phosphate is 48.1%.

Here we have nickel phosphate - Ni₃(PO₄)₂

In this formula there are-

3 Ni atoms , 2 P atoms and 8 O atoms

now, the molecular mass nickel phosphate is- = 3 × molar mass of Ni + 2 × molar mass of P + 8 × molar mass of O

Now we know that -

molar mass of Ni = 58.7u

molar mass of P = 31u

molar mass of O = 16

So that here-

molecular mass of nickel phosphate = 3 × 58.7 + 2 × 31 + 8 × 16 = 176.1 + 62 + 128 = 366.1u

Now, mass of nickel in nickel phosphate = 3 × 58.7  = 176.1u

And for mass percentage - mass percentage = ( mass of nickel / mass of nickel phosphate ) × 100 =  (176.1 / 366.1) × 100 = 48.10 %

Hence we can conclude that the mass percentage of nickel in nickel phosphate came out to be 48.1 % after applying all the concepts.
