100 ml of 0.1 M solution A is mixed with 20ml of 0.2 M solution B. The final molarity of the solution is :

A

0.12 M

B

0.15 M

C

0.18 M

D

0.21 M

Text Solution

Verified by Experts

The correct Answer is:
A
Moles of A in 100 ml `=(0.1xx100)/(1000)=0.01`
Moles of B in 20 ml `=(0.2xx20)/(1000)=0.004`
Total moles `= 0.01+0.004=0.014`
Molarity `= (0.014)/(120)xx1000=0.117=0.12` M
