Two glucose solution are mixed. One has a volume of `480 mL` and a c oncentration of `1.50 M` and the second has a volume of `250 mL` and concentration `1.20 M`. The molarity of final solution is

A

`1.20 M`

B

`1.50 M`

C

`1.344 M`

D

`2.70 M`

Verified by Experts

The correct Answer is:

C

`M_(1) V_(1) + M_(2) V_(2) = M_(3) V_(3)`
`(V_(3) = V_(1) + V_(2))`
`1.5 xx 480 + 1.2 xx 520 = M_(3) xx 1000`
`M_(3) = 1.344 M`
