Question

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

Answer 1

Mass of solute sugar = 25g

Mass of solvent water = 250g

Mass of solution = Mass of solute + Mass of solvent

= 25g + 250g

= 275g

Therefore

Mass Percentage solution  

$\bf\huge\frac{Mass\:of\:Solute}{Mass\:of\:Solution}\times 100$

$\bf\huge => \frac{25}{275}\times 100$

= 9.09%

Percentage in m/v  

$\bf\huge\frac{Mass\:of\:solute}{Volume\:of\:Solution}\times 100$

Answer 2

Answer:

Mass of solute sugar = 25g

Mass of solvent water = 250g

Mass of solution = Mass of solute + Mass of solvent

= 25g + 250g

= 275g

Therefore

Mass Percentage solution  

\bf\huge\frac{Mass\:of\:Solute}{Mass\:of\:Solution}\times 100  

\bf\huge => \frac{25}{275}\times 100  

= 9.09%
