A solution is made by diluting 18.2 g glucose (C6H12O6) in 0.150 kg water. What is the mass percentage of solute in this solution?

What is .0182/(.150+.0182)

23 10.08%

To find the mass percentage of solute in a solution, we need to calculate the mass of the solute (glucose) and the total mass of the solution.

Given:
Mass of glucose (solute) = 18.2 g
Mass of water (solvent) = 0.150 kg = 150 g (since 1 kg = 1000 g)

Total mass of the solution = Mass of glucose + Mass of water
Total mass of the solution = 18.2 g + 150 g = 168.2 g

Now we can find the mass percentage of solute using the formula:

Mass percentage = (Mass of solute / Total mass of solution) x 100

Mass percentage = (18.2 g / 168.2 g) x 100

Calculating this gives us:
Mass percentage = (0.108 x 100) ≈ 10.8%

Therefore, the mass percentage of solute (glucose) in this solution is approximately 10.8%.
