Given in the question is mass percent of glucose its value is 15 .5 percent we know that 15 .5 percent means 15 .5 grams of glucose is presenting 100 grams solution.
00:29
Here solution is equal to solute plus solvent so therefore solution is 100 grams 100 gram solution is equals to solute solute is 15 .5 grams glucose 15 .5 grams plus solvent is water let us solve this for water that is solvent calculation solvent equal to 100 minus 15 .5, 84 .5 grams solvent.
01:18
Molality of the solution is given by the formula.
01:23
Molality of solution is equals to mole of solute divided by mass of solvent in kz.
01:44
This is equals to mass of solute.
01:51
Divided by molecular weight of solute multiplied with mass of solvent.
02:07
Mass of solvent is given in kg.
02:11
Morality of glucose, let us find out.
02:15
Morality of glucose.
02:20
Let us apply this for glucose...
