Question

2.5 litre of 1 M NaOH solution mixed with another
3 tre of 0.5 M NaOH solution. Then find out
molarity of resultant solution.​

Answer 1

this is the concept of acid +acid mixing.

so we can calculate the Molarity of final solution with the help of given formula .

M = M1.V1 +M2. V2

final. V1 +V2

=}. 1×2.5 +0.5 ×3

2.5+3

=}. 4 = 0.72 M

5.5
