Question: If 10 g of glucose (C6H12O6) is dissolved in 200 g of water, what is the mass percentage of the solution? (2023)

Options:

Correct Answer: 4.76%

Exam Year: 2023

Solution:

Mass percentage = (mass of solute / mass of solution) x 100. Mass of solution = 10 g + 200 g = 210 g. Mass percentage = (10 g / 210 g) x 100 = 4.76%.

If 10 g of glucose (C6H12O6) is dissolved in 200 g of water, what is the mass percentage of the solution? (2023)

If 10 g of glucose (C6H12O6) is dissolved in 200 g of water, what is the mass percentage of the solution? (2023)

Step 1: Identify the mass of the solute (glucose) which is 10 g.
Step 2: Identify the mass of the solvent (water) which is 200 g.
Step 3: Calculate the total mass of the solution by adding the mass of the solute and the mass of the solvent: 10 g + 200 g = 210 g.
Step 4: Use the mass percentage formula: Mass percentage = (mass of solute / mass of solution) x 100.
Step 5: Substitute the values into the formula: Mass percentage = (10 g / 210 g) x 100.
Step 6: Calculate the mass percentage: (10 / 210) x 100 = 4.76%.

Mass Percentage – The mass percentage is a way to express the concentration of a solute in a solution, calculated as the mass of the solute divided by the total mass of the solution, multiplied by 100.
Solution Composition – Understanding how to calculate the total mass of a solution by adding the mass of the solute and the solvent.
