How many mole of magnesium phosphate Mg(...

How many mole of magnesium phosphate `Mg_(3)(PO_(4))_(2)` will contain `0.25 "mole"` 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:
B
`8 "mole of" O-"atom"equiv"mole" Mg_(3)(PO_(4))_(2)`
`0.25"mole of" O-"atom"=(1xx0.25)/(8)`
`=3.125xx10^(-2)"mole of" Mg_(3)(PO_(4))_(2)`
