Question

What is a saturated solution?Calculate the mass of glucose and mass of water required to make 250g of 25% solution of glucose.​

Answer 1

Answer:

A solution which can not dissolve further amount of solute at a particular temperature is called saturated solution. For example, when you keep adding sugar to the water, a time will reach when no more sugar will dissolve in the water and sugar will settle down at the bottom.

Mass of glucose = 62.5 g

Mass of water = 187.5 g

Explanation:

Given :-

Mass percentage = 25%

Mass of solvent = 250 g

To Find :-

Mass of water

Mass of glucose

Solution :-

We know that,

Mass percentage = mass of solute / mass of solvent x 100

---------------------------

Here,

Mass % = 25

Mass of solvent = 250 g

--------------------------

25 % = Mass of solute/ 250 x 100

Mass of solute = 25 x 250/100

= 6250/100

= 62.5 g

-------------------------

Mass of water = Mass of solution - Mass of solute

= 250 - 62.5

= 187.5 g
