Question

Calculate the molauity of final solution if 4l water is added to
2l of 1molar hcl​

Answer 1

Answer:

Firstly I am clearing the question that it is 1M hcl solution with volume 2l

So the no. Of moles of hcl are 2*1 =2 ( as molarity = no. Of moles/ volume of solution in litres)

Now the moles are 2 and we have added 4 litre of water

So resulting molarity = 2/2+4

= 2/6

=1/3M= 0.33M
