Question

If Cylinder C contains a 40.0 % sucrose solution (40.0 g suger per 100 mL of
solution), how much sucrose is present?

Answer 1

We are only given the concentration but the volume of the solution is not given.

Assuming that we are talking about 1L of solution;

40g of glucose are in every 100mL of solution

How many grams would be in 1L (1000mL)

Mass of glucose $=\dfrac{40g x 1000mL}{100mL} = 400g$ of glucose
