If 1 litre of 2.2M sulphuric acid is poured into a bucket containing 10 litres of water and the resulting solution mixed thoroughly, the resulting sulphuric acid concentration will be
2.2M
1.1M
0.2M
0.11M
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
