What volume of 17.8 M stock sulfuric acid solution would be needed to make 2.0L of 0.200 M diluted sulfuric acid solution?

Required Volume is 22.47ml

Explanation:

To make 2.0L of 0.2M sulfuric acid required moles = 0.2 x 2 = 0.4 moles

To get 0.4 from 17.8M required quantity = 1000/17.8 x 0.4 = 22.47ml

out of these options:
