Question

calculate the mass of glucose and mass of water required to make 250 g of 25% of solution

Answer 1

concentration of glucose= 25%

m of solute/mass of solution x 100 = 25

m of solute/250 x 100 = 25

m of solute = 25/100 x 250 =62.5 g

Answer 2

The mass of water and glucose required is 187.5 g and 62.5 g

Given:

Concentration of the glucose = 25% = 0.25

To find mass of the glucose:

We know that the formula to find the concentration of the solution is given below:

$\Rightarrow \frac{Mass \ of \ the \ solute}{Mass \ of \ the \ solution \times 100}$

Therefore,

$\frac{\text {Mass of the solute}}{250 \times 100}=0.25$

$Mass \ of \ the \ solute = 0.25 \times 250 \times 100 = 62.5 \ grams$

Hence the mass of the solute (glucose) is = 62.5 grams

To find mass of the water:

Mass of the water = Mass of the solution - Mass of the solute

= 250 - 62.5

Hence, mass of the water = 187.5 grams
