Question

400 ml of 2M NaOH solution is mixed with 600 ml of 1M NaOH solution .the final molarity of solution becomes​

Answer 1

Answer:

Explanation:

M1V1+M2V2=M(V1+V2)

800+600=M(1000)

M=1.4

Answer 2

Answer:

FORMULA TO CALCULATE RESULTANT MOLARITY IS :M1V1 +M2V2/V1+V2

SO BY USING THIS.

(400×2+600×1)/400+600

=1.4 M
