Question

Calcutate the mass percentage of calcium and phosphorus in calcium phosphate

Answer 1

Answer:

Explanation:

Given:

Calcium Phosphate Ca3(PO4)2.

To Find:

The mass percentage of calcium and phosphorous.

Calculation:

- The molar mass of Calcium Phosphate, W = 310 gm

- The mass of Calcium in Calcium Phosphate, w1 = 40×3 = 120 gm

- The mass of Phosphorous in Calcium Phosphate, w2 = 31×2 = 62 gm

- The mass % of calcium = (w1/W)×100 = (120/310)×100

⇒The mass % of calcium = 38.71 %

- The mass % of phosphorous = (w2/W)×100 = (62/310)×100

⇒The mass % of phosphorous = 20 %

- So, the mass percentage of Calcium and Phosphorous in Calcium Phosphate is 38.71 % and 20% respectively.
