Text Solution

Verified by Experts

The correct Answer is:

10 g of CaCO_(3) contains :

10 moles of `CaCO_(3)`

0.1 g atom of Ca

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

0.1 equivalent of Ca

10 g of CaCO_(3) contains

10 moles of `CaCO_(3)`

`0.1 g` atom of `Ca`

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

0.1 of equivalent of `Ca`

250 ml of a calcium carbonate solution contains 2.5 grams of CaCO_(3) . If 10 ml of this solution is diluted to one litre, what is the concentration of the resultant solution ?

0.1 M

0.001 M

0.01 M

`10^(-4)M`
