Hi there.
00:04
This question is a dilution problem.
00:06
In a dilution problem, we start with a stock solution of a certain concentration, and we take a certain volume of that, and then we add more solvent to it to dilute it, giving us a less concentrated solution.
00:24
Anytime we have a dilution problem, we can use the equation m1 times v1 equals m2 times v2 to solve it.
00:35
Where m is molarity, v is volume, the ones represent the stock or the initial concentrated solution, and the twos represent the diluted solution.
00:45
Well, in this question, we have a concentrated solution that has a molarity of 15 .1 molar.
00:53
And we want to know what volume of that we have to use if we want to make a 0 .250 molar solution, and we want to make 1 ,750 milliliters of that...
