Question

10.6 g of a substance of molecular weight 106 was dissolved in 100 ml. 10 ml of this solution was
pipetted out into a 1000 ml flask and made up to the mark
and made up to the mark with distilled water. The moranty
resulting solution is
1) 1 M
2) 10^-2 M
3) 10^-3M
4) 10^-4 M​

Answer 1

10.6 g of a substance of molecular weight 106 was dissolved in 100 ml. 10 ml of this solution was

pipetted out into a 1000 ml flask and made up to the mark

and made up to the mark with distilled water. The moranty

resulting solution is

1) 1 M

2) 10^-2 M

3) 10^-3M

4) 10^-4 M

Hope it helps you

Answer 2

Answer:

Answer is 10^-2

Explanation:

M= W ×1000×1

V MW

on substituting we get M= 1

From the formula

M1V1 = M2V2

1×10 = M2 × 1000

so, M2 = 1

100

M2= 10^-2

If you wish please make it in a brain list
