Answer : 42.3 ml of a 0.266 M
solution are required.
Solution : Given,
Molarity of
solution 1 = 0.266 M
Molarity of
solution 2 = 0.075 M
Volume of
solution 2 = 150 ml = 0.150 L (1 L = 1000 ml)
Formula used :

where,
= Molarity of
solution 1
= Molarity of
solution 2
= Volume of
solution 1
= Volume of
solution 2
Now put all the given values in above formula, we get
(1 L = 1000 ml)
Therefore, 42.3 ml of a 0.266 M
solution are required.
