Correct Answer: Option C
Explanation

Given:

C1 = 2.2 M , V1 = 1 Litre , C2 = ?  V2 = 1 + 10 Litres ( because the volume of water has increased) = 11 Litres

Using the relationship C1V1 = C2V2

                                     2.2 X 1 = C2 X 11

                                         C2 = 2.2 /11

                                              = 0.20 M - Option C

There is an explanation video available below.
