`10g` 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
Mol. Wt of `Ca CO _(3) = 40 + 12 + 48 = 100`
Moles of `Ca CO _(3) `in `10 g = (10)/(100) = 0.1 mol = 0.1` g atom
