In this question, we need to determine the molar concentration of a certain calcium hydroxide solution.
00:09
And the mass of the calcium hydroxide solute that is in solution is given as 0 .185 grams.
00:19
And we're working with a volume of 100 milliliters of this specific calcium hydroxide solution.
00:28
Right so if we think about molar concentration that we need to calculate we need to think about this in terms of number of moles per calcium hydroxide per one liter solution right so keep that in the back of your mind while starting off with what we have we have zero 1 .185 grams of calcium hydroxide per.
01:09
We have this in a solution of 100 milliliters.
01:15
Right.
01:16
So this is per 100 milliliters.
01:18
But now, when i work with molar concentration, i usually work in terms of moles per liter.
01:26
So i don't want to have milliliters.
01:29
Yeah, i want to have liters.
01:31
So i'm going to convert the water.
01:33
100 milliliters here to liters.
01:36
So 100 milliliters is the same as 0 .10 .0 liters of solution.
01:47
Right...
