Answer 1

QUESTION:

Find the concentration of solution in terms of weight percent if 20 gram of sugar is dissolved in 40 gram of water.

ANSWER:

• Concentration of solution in terms of weight percentage = 33.33 % .

GIVEN:

• 20 gram of sugar is dissolved in 40 gram of water.

TO FIND:

• Concentration of solution in terms of weight percentage.

EXPLANATION:

$\bigstar \ \boxed{ \bold{ \large{ \gray{Weight \ \% = \dfrac{Wt. \ of\ solute}{Wt.\ of\ solution} \times 100}}}}$

$\implies \textsf{Weight of solute = 20 g}$

$\implies \textsf{Weight of solution = 40 + 20 = 60 g}$

$\sf \hookrightarrow Weight \ \% = \dfrac{20}{60} \times 100\ \%$

$\sf \hookrightarrow Weight \ \% = \dfrac{1}{3} \times 100\ \%$

$\sf \hookrightarrow Weight \ \% = 33.33\ \%$

Hence the concentration of solution in terms of weight percentage = 33.33 %.

SIMILAR QUESTION:

Determine the volume/volume percent solution made by combining 25 mL of ethanol with enough water to produce 200 mL of the solution.

ANSWER:

• Concentration of solution in terms of volume percentage = 12.5 % .

GIVEN:

• 25 mL of ethanol is combined with water to produce 200 mL of the solution.

TO FIND:

• Concentration of solution in terms of volume percentage.

EXPLANATION:

$\bigstar \ \boxed{ \bold{ \large{ \green{Volume \ \% = \dfrac{Vol. \ of\ solute}{Vol.\ of\ solution} \times 100}}}}$

$\implies \textsf{Volume of solute = 25 mL}$

$\implies \textsf{Volume of solution = 200 mL}$

$\sf \leadsto Volume \ \% = \dfrac{25}{200} \times 100\ \%$

$\sf \leadsto Volume \ \% = \dfrac{25}{2} \ \%$

$\sf \leadsto Volume \ \% = 12.5\ \%$

Hence the concentration of solution in terms of volume percentage = 12.5 %.
