Okay, so to solve for this, we have here 0 .2 .0 mol.
00:10
Okay, so i will assume this is molality, so moles per kilogram.
00:15
All right? so assume that we have one kilogram of the solvent.
00:23
So from this value, we can calculate the moles of subute, since we have 0 .20 mole of subute per kilogram.
00:34
Of solvent, multiply the mass of the solvent, we have assumed one kilogram of solvent.
00:44
And you're able to cancel this and you should get 0 .2 -00 -mole -up solute.
00:51
Okay, so we are to calculate here the percent mass over volume.
00:57
So this is mass -absolute over the volume of the solution.
01:01
Right? so we have 0 .2 -00 more of a solute.
01:07
Is mg3c6, sorry, it should be c6h5 -07, 2, and then convert this to grams since that's the numerator mass.
01:22
So the molar mass for this is 451 .15 grams per mole.
01:28
Okay, so we'll be able to cancel this.
01:31
There are many units now and the numerator is grams, divided by the volume of the solution.
01:36
So that's volume of the solution in ml...
