If 1 litre of 2.2M sulphuric acid is poured into a bucket containing 10 litre of water,and resulting solution mixed thoroughly, the resulting sulpuric acid concentration will be?
2.2 M
1.1 M
O.22 M
0. 11 M
0.20 M
Explanation
Given:
C\(_1\) = 2.2 M , V\(_1\) = 1 Litre , C\(_2\) = ? V\(_2\) = 1 + 10 Litres ( because the volume of water has increased) = 11 Litres
Using the relationship C\(_1\)V\(_1\) = C\(_2\)V\(_2\)
2.2 X 1 = C\(_2\) X 11
C\(_2\) = \(\frac{2.2}{11}\)
= 0.20 M - Option E
