Answer:
Li₃PO₄ has 18 % of Li
Explanation:
First of all we determine the molar mass of Lithium phosphate
Molar mass: 115.79 g/ mol
1 mol of lithium phosphate has:
3 moles of Li → 20.82g
The mass percent composition of lithium will be:
(Mass of Li / Total mass) . 100 → (20.82 g / 115.79 g) . 100 = 18 %
