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.
