Question

Calculate the mass of glucose and mass of water required to make 250 gram of 25% solution of glucose

Answer 1

Answer :-

• 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

Answer 2

hello there

Explanation:

Question: Calculate the mass of glucose and mass of water required to make 250 gram of 25% solution of glucose?

Solution:

Given:

Mass % of solution = 25%

Mass of solution = 250 g

Let, Mass of the solute (Glucose) be = x gm

Therefore,

Mass of the solution (water) will be = ( 250 -x ) gm

Now , To calculate the mass of both solute and solution we have to apply the formulae of Mass %

i.e,

$mass\% = \frac{mass \: ofsolute}{mass \: of \:solution } \times 100$

Now ,

[ Puting the values of the various variables in the formulae accordingly. ]

■

$mass\% = \frac{x}{250} \times 100$

Here, mass % is 25

So, putting the value of mass% in the formulae.

$25 = \frac{x}{250} \times 100$

■ 25 ×250 = 100 × x

■ x = 6250 / 100

■ x = 62.5 grams

[ Now , putting the value of x ,inorder to find the mass of both solute and solvent ]

Therefore:.

______________________________

[ Mass of Glucose (solute) = 62.5 g]

Mass of Water (solvent) = (250 - 62.5) gm = 187.5 g ].
