Two solutions of a substances (non electrolyte) are mixed in the following manner. 480 ml of `1.5M` first solution `+520 mL` of `1.2M` second solution. What is the molarity of the final mixture?

A

1.20 M

B

1.50 M

C

1.344 M

D

2.70 M

Text Solution

Verified by Experts

The correct Answer is:
C
`M_1V_1 +M_2V_2 = M_3V_3` ,
`1.5xx480 +1.2 xx 520 = Mxx1000 `
`M = (720 +624)/1000 = 1.344 M.`
