Explanation:
According to the dilution law,

where,
= concentration of stock solution = 20X
= volume of stock solution = ?
= concentration of required solution= 1X
= volume of required solution= 50 ml


Thus 2.5 ml much of a 20X tricaine stock solution is needed to dilute in order to make your solution.
