Answer: The mass of phosphorus that is present for given amount of calcium is 28.53 g.
Explanation:
We are given:
Mass of calcium = 50 grams
The chemical formula of calcium phosphate is [tex]Ca_3(PO_4)_2[/tex]
Molar mass of calcium = 40 g/mol
Molar mass of phosphorus = 31 g/mol
In 1 mole of calcium phosphate, 120 grams of calcium is combining with 62 grams of phosphorus.
So, 50 grams of calcium will combine with = [tex]\frac{62}{120}\times 50=28.53g[/tex] of phosphorus.
Hence, the mass of phosphorus that is present for given amount of calcium is 28.53 g.
