Hello students in the question we have been given calcium chloride and the percentage mass of it has been given as 18 .2%.
00:11
Also we have been given the density.
00:15
Density of this solution is nothing but 1 .18 grams per emm.
00:21
We have been asked to calculate the molarity of this solution.
00:27
So they are asking the molarity.
00:29
So now first of all let us calculate the voluarty.
00:31
So now first of all let us calculate the voluality.
00:32
We know we will use two formula over here.
00:35
One formula is that density is equal to nothing but mass by volume and molarity.
00:47
If we calculate a molarity of a solution, what is the formula that we use is number of moles of salute.
00:53
Over here it is c .cl2 divided by volume of solution in liters, definitely.
01:00
So now using these two formulas we will solve this question.
01:02
So first of all, let us assume...
