How many moles of magnesium phosphate Mg...

How many moles of magnesium phosphate `Mg_3 (PO_4)_2` will contain 0.25 mole of oxygen atoms ?

A

`2.5xx10^(-2)`

B

0.02

C

`3.125xx10^(-2)`

D

`1.25xx10^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
C
8 mole O contained by `to 1 "mole" Mg_(3)(PO(4)_(3))`
1 mole O contained `(1)/(8) "mole" Mg_(3)(PO(4)_(2))`
by
0.25 "mole" O is ` rArr (1)/(8)xx0.25` "mole" `Mg_(3)(PO(4))_(3)`
contained by ` = 3.125 xx10^(-2)` mole `Mg_(3)`
