Answer 2

Answer:

(b) 0.16M

Explanation:

As per the data given,

200 mL of 0.1M HCl  when added with

300mL of 0.2M HCl give a solution of

500mL of some concentration

M1 = 0.1M

M2 = 0.2M

V1 = 200mL

V2 = 300mL

The relation to find the molarity of final solution is given as,

M1*V1 + M2*V2 = M*V

0.1*200 + 0.2*300 = M* 500

We get ,

M = 0.16Molar Answer
