10.6 gram of a substance of molecular weight 106 was dissolved in 100ml . 10 ml of this solution was pipetted out into a 1000ml flask and made up to the mark with distilled water. The molarity of the resulting solution is

A

`1.0M`

B

`10^(-2)M`

C

`10^(-3)M`

D

`10^(-4)M`

Text Solution

Verified by Experts

The correct Answer is:
B
No. of moles of solute = 10.6/106=0.1
100mL of solution contains = 0.1 mole of solute
10mL of solution contains =0.01 mole of solute
Molarity of solution after dilution = 0.01/1L
