Explanation:
N(Ca)=3×N(Ca₃(PO₄)₂)=
=3×2.3×10²³=6.9×10²³
6.02×10²³→40g
6.9×10²³→Xg
m(Ca)=X≈45.85g

hi 5th grader, stop trying to cheat :)
Explanation:
volume of Ni = 25 nL = 25 x 10⁻⁹ L
mol Ni = 25 x 10⁻⁹ L x 1.25 mol/L = 3.125 x 10⁻⁸
mass = mol x Ar Ni
mass = 3.125 x 10⁻⁸ x 59 g/mol
mass = 1.84 x 10⁻⁶ g = 1.84 μg
