Given: A = 0.1 M V1 = 100ml
B = 0.2 M V2 = 25 ml
Mab = (m1v1 + m2v2)/v1 +v2
= (100 x 0.1 + 25 x. 0.2) / (100 + 25) = 0.12M
Final Molarity of Solution = 0.12 M
B = 0.2 M V2 = 25 ml
Mab = (m1v1 + m2v2)/v1 +v2
= (100 x 0.1 + 25 x. 0.2) / (100 + 25) = 0.12M
Final Molarity of Solution = 0.12 M

substitute the values in this formulae mab=ma x va +va x vb÷va+ vb then you would get the answer 0.12
