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

2.70M

B

1.344 M

C

1.50 M

D

1.20 M

Text Solution

Verified by Experts

The correct Answer is:
B
Total molarity `=(M_(1) V_(1)+M_(2)V_(2))/(V_(1) + V_(2))`
`(1.5 xx 480 + 1.2 xx 520)/(480 + 520)=1.344 M `
