Question

In a chemistry class, Gabby prepared a solution by mixing 25 grams (g) of sugar in 80g of water. What are the concentration of the solute and solvent in percent (%) by mass?

Answer 1

Answer:

Solute concentration is 23.81% and solvent concentration is 76.19%.

Explanation:

Solute = 25 g of sugar

Solvent = 80 g of water

Solute concentration

$\dfrac{\text{Solute}}{\text{Solute+Solvent}}\times 100=\dfrac{25}{25+80}\\ =23.81\%$

Solvent concentration

$\dfrac{\text{Solvent}}{\text{Solute+Solvent}}\times 100=\dfrac{80}{25+80}\\ =76.19\%$

The solute concentration is 23.81% and solvent concentration is 76.19%.
