Question

Calculate the mass of water and mass of glucose required to make 250 g of 50% Solution of Glucose

Answer 1

Explanation:

We know that,

Mass percent = mass of solute / mass of solution

Here mass of solution = 250g

Mass of solute = X

Mass percent = 40

Hence 40% = X/250

Therefore X = 100g

Hence amount of solute needed to make 250g of 40% solution is 100g

As we know mass of solution = mass of solute + mass of solvent,

Therefore mass of solute = 250g – 100g

$= 150$

Answer 2

To calculate the mass of water and mass of glucose required to make 250 gm of 50% Solution of Glucose,we have to apply a theory which is explained below

•We know that,

Mass percent = mass of solute / mass of solution

Here mass of solution = 250 gm

Mass of solute = X

Mass percent = 40

Hence 50% = X/250

Therefore X = 125 gm

Hence amount of solute needed to make 250 gm of 50% solution is 125 gm

As we know mass of solution = mass of solute + mass of solvent,

Therefore mass of solute = 250 gm – 125 gm

Hence the mass of solute = 125 gm
