Calculate the amount of glucose required to prepare 250g of 5% solution of glucose by mass.​

Answer 1

Answer:

Expert Answer:

(a) Percentage of solution = 5.

Mass of solution = 250g.

= Mass of solute / 250 x 100.

= 5 x 250 / 100.

= 12.5g.

(b) Dispersed phase - the solute like component in a colloid form the dispersed phase.

Dispersed medium - the component in which the dispersed phase is suspended is the dispersed medium.

Answer 2

${\large{\underline{\underline{\pmb{\frak{Let's\;understand\;the\;concept:-}}}}}}$

☀️  As per the given information, we have mass of glucose solution and percentage of concentration of glucose in it. We need to calculate the mass of glucose we must add. Basically, we’ve to put the values in the formula of finding the concentration in order to get the required answer.

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

${\large{\underline{\underline{\pmb{\frak{Given:-}}}}}}$

Mass of glucose solution is 250g

Concentration of glucose in it is 5%

${\large{\underline{\underline{\pmb{\frak{To\;find:-}}}}}}$

Mass of glucose required [ mass of solute ]

${\large{\underline{\underline{\pmb{\frak{solution:-}}}}}}$

❍  To calculate the concentration of the solution we must know that ::  

$\sf \bigstar \;\; Concentration\;of\;solution = \dfrac{Mass\;of\;Solute}{Mass\;of\;Solution} \times 100 \%$

Where,

• Solute is amount of glucose we need

• Mass of solution is 250g

 

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

Finding the Mass of solution :-

⤳ 5 = Mass of Solute/250 × 100  

⤳ 5 × 250 = 100 × Mass of Solute  

⤳ Mass of Solute × 100 = 1250

⤳ Mass of Solute = 1250/100  

⤳ Mass of Solute = 125/10  

⤳ Mass of Solute = 12.5g

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━

• Henceforth, the amount of glucose required is 12.5g
