Question

A sample of calcium phosphate contain 8 mole of O Atoms.The number of mol of Ca atoms in the sample is

Answer 1

formulae of calcium phosphate= Ca3(PO4)2
O atoms=8
Ca atoms=3
No. of moles of Ca atoms=3

Answer 2

Answer: There are 3 moles of calcium atoms in the the sample.

Explanation:

The formula for calcium phosphate is $Ca_3(PO_4)_2$

In the given formula, there are 3 elements which are calcium, phosphorous and oxygen.

The formula of $Ca_3(PO_4)_2$ has 3 moles of calcium atoms 2 moles of phosphorus atoms and 8 moles of oxygen atoms.

Hence, there are 3 moles of calcium atoms in the the sample.
