What is the mass percent of in sugar a solution prepared by adding 34.0 g to 89.3 g of water?

To find the mass percent of sugar in the solution, we need to calculate the total mass of the solution first.

Total mass of solution = mass of sugar + mass of water
Total mass of solution = 34.0 g + 89.3 g
Total mass of solution = 123.3 g

Now, we can find the mass percent of sugar in the solution using the formula:

Mass percent = (mass of solute/mass of solution) x 100%
Mass percent = (34.0 g/123.3 g) x 100%
Mass percent = 0.2758 x 100%
Mass percent ≈ 27.6%

Therefore, the mass percent of sugar in the solution is approximately 27.6%.
