`400 cm^(3)` of water is added to 6% of 600 g (molar mass =36) of a solute. The molarity contain 20 millimoles of the solute is

A

3

B

1.5

C

0.25

D

1

Text Solution

Verified by Experts

The correct Answer is:
C
6% of 600 gm = `W_(2) = 36g`
`C=W/("Molar mass" xx V(dm^(3)))`
`C=36/(36 xx 0.4)=1/(0.4)=0.25`
