How many moles of magnesium phosphate, `Mg_(3)(PO_4)_2` will contain `0.25` moles of oxygen atoms ?

A

`0.02`

B

`3.125xx10^-2`

C

`1.25xx10^-2`

D

`2.5xx10^-2`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
8 mol of `O=1 ` mol of `Mg_(3)(PO_4)_2`
0.25 mol `O=(1xx0.25)/(8)` mol of `Mg_(3)(PO_4)_2`
`=3.125xx10^-2 ` mol of `Mg_(3)(PO_4)_2`.
