Hello, so we're going to start up by using the formula to delta tf which is equal to i times kf times m.
00:14
So the delta t f is going to be 0 minus minus 1 .03.
00:21
So here i is going to go to 1 because the compound that's not dissociating water.
00:28
It's going to be 1 .3 is a constant, which is 1 .86 times m.
00:38
So you're going to get m to be equal to 0 .55 -376.
00:51
It's going to be more per kilogram.
00:57
So what this means is that the .55376 is more of soviet is going to be present in 1 kilogram or 1 ,000.
01:08
Gram of water okay so we go ahead and get the the mass or the weight of the salute the weight of the solution that's just gonna be 0 .55 376 times m so where m is the molar mass of the solid right this is just gonna give us the molar mass or i mean that's going to give us the weight okay then the weight of the solution that's going to be the combination or the addition of the solute and the water.
02:00
Okay.
02:01
So the water is a thousand grams or one two -gram plus that of the solid right that's going to be 0 .55376 m right and the volume of the solution that's going to be the mass over the density right or the weight of the solution divided by the density of the solution.
02:43
So our solution for this solution, okay...
