Question

Calculate the mass percent of Calcium prosperous and oxygen in calcium phosphate ca2(pO4)2

Answer 1

Answer:

Molar mass of Calcium Phosphate = Ca₂(PO₄)₂

= (40*2)+2[31+(16*4)] g

= 80+2[31+64] g

= 80+2[95] g

= 80+190 g

= 270 g

Molar Mass of Calcium  = 2*40 g = 80 g

Molar Mass of Oxygen = (16*4*2) g = 64*2 g = 128 g

Mass Percent of Calcium = 80/270*100 % = 29.62%

Mass Percent of Oxygen = 128/270*100 % = 47.40%

Hope this helps.
