4 litres of water are added to 2 litres 6 molar hydrochloric acid solution. What is the molarity of the resulting solution ?

Text Solution

Verified by Experts

The correct Answer is:
2 M
Total volume of the solution after mixing `=(4+2)=6L`
By applying molarity equation :
`overset(("dilute"))(M_(1)V_(1))-=overset(("conc."))(M_(2)V_(2))`
`M_(1)xx6=6xx2orM_(1)=(6xx2)/(6)=2M`.
