Two solutions of a substance (non-electroyte) are mixed in the following manner `480 mL` of `1.5M` of first solution with `520 mL or 1.2M` of second solution. The molarity of final solution is:

A

(a)1.20 M

B

(b)1.50 M

C

(c )1.344 M

D

(d)2.70 M

Text Solution

Verified by Experts

The correct Answer is:
C
For I mM=`480xx1.5=720`
For II mM=`520xx1.2=624`
Total millimoles`=720+624=1344`
`:. M=1344/(480+520)=1.344 M`
