First of all, let's have a look what all is given in the problem.
00:05
Given is molecular formula of cholesterol is given.
00:09
That is, molecular formula of cholesterol is c -27h -46 -o.
00:18
This is the molecular formula of cholesterol given, and the molarity is also given.
00:24
Mularity is given as 0 .005 molar, and the volume is given as 750 ml.
00:35
What we are supposed to find out, we need to find the mass of cholesterol.
00:42
We have to find the grams of cholesterol that is required.
00:47
So we can say that we need to find the mass.
00:50
For this, first we should know the formula of the mularity with the help of which we can easily calculate number of moles.
00:57
Mularity is nothing but number of moles by volume in liters.
01:01
So here the molarity that is given is 0 .005 equals to number of moles divided by volume in liters...
