Question

Which of the following sugar solutions is the most concentrated? *
a. 20 grams of sugar dissolved in 100 mL of water
b. 30 grams of sugar dissolved in 100 mL of water
c. 30 grams of sugar dissolved in 200 mL of water
d. 50 grams of sugar dissolved in 100 mL of water

Answer 1

Answer:

c is the best answer of the day

Answer 2

50 grams of sugar dissolved in 100 mL of water is the most concentrated sugar solutions compared to the others.

• A concentrated solution means that the solution has a higher amount of dissolved solute compared to the solvent.
• To calculate the concentration, the mass of solvent is divided by the volume of water and multiplied by 100
• From the above options if we see concentration of option D is highest, which is 50 / 100 × 100 = 50%
• While the other options have a low concentration than 50%
