Question

How much water would you need to add to 10mL of 6.0M HCl, to produce a solution that is 0.2M?

a. 300
b. 290
c. 30
d. 3.0

Answer 1

We will use Law of dilution for finding the volume here

$M_1V_1=M_2V_2$

$10\times6=x\times0.2$

x=300 mL will be total volume of solution

So, volume of water added= 300 -10 = 290 mL
