The number of oxygen atoms present in `14*6 g` of magnesium bicarbonate is

A

`6N_(0)`

B

`0*6N_(0)`

C

`N_(0)`

D

`N_(0)//2`

Text Solution

Verified by Experts

The correct Answer is:
B
Magnesium bicarbonate is `Mg(HC)_(3))_(2)` 146 g of `Mg((HCO_(3))_(2)` contains O atoms = `6N_(0)`
`:. 14*6 g` of `Mg(HCO_(3))_(2)` contains O atom
`=0*6 N_(0)`
