10 g of CaCO(3) contains :...

10 g of `CaCO_(3)` contains :

A

10 moles of `CaCO_(3)`

B

`0.1 g` atom of `Ca`

C

`6 xx 10^(23)` atoms of `Ca`

D

0.1 of equivalent of `Ca`

Text Solution

Verified by Experts

The correct Answer is:
B
`Mw_(2) "of" CaCO_(3) = 40 + 12 + 48 = 100`
Moles of `CaCO_(3)` in `10 g = (10)/(100)`
`= 0.1 "mol" = 0.1 g` atom
