So this question asks you which solution has greater osmotic pressure.
00:07
So this question, you have to first of all know the molarity.
00:10
So basically, the solution has higher, let's write it down, higher molarity, which means it will have a higher osmotic pressure.
00:39
So they are proportional.
00:42
So this is how we judge which solution is.
00:46
Who has a greater osmotic pressure.
00:49
Let's look at a.
00:50
A is basically talk about table sugar.
00:53
So you have two table sugar solutions.
01:01
One has 5 .5 percent and then the other is 8 .5 percent.
01:13
Now from there you can see that this means 5 .5 gram of sugar in 100 ml of solution.
01:23
This is 5 .5 % and then the other one is 8 .5 % this means you have 8 .5 gram of sugar in 100 ml so they are both table sugar that means their molecular weight is the same so this means that when you have less mass of table sugar in a solution it has lower concentration or lower molarity because molarity and the mass is also proportional at 8 .5 you have more mass of the table sugar it has higher mole in there this one has a higher molarity so from there you can see that higher molarity has higher osmotic pressure this one has higher osmotic pressure so you don't really have to do the calculation you know that they're the same material cell solute the one has higher mass obviously have high more moles or higher molarity and then higher osmotic pressure that's it so the 8 .5 percent has higher osmotic pressure b b is a 1 .4 mole molar of sodium chloride and then the other one is 5 .2 molar of of sodium chloride...
