Question

A student placed 11.0 of glucose (C6H12O6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100.-ml mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 50.0ml- sample of this glucose solution was diluted to 0.500L . How many grams of glucose are in 100.ml of the final solution?

Answer 1

11.0 g/100 mL = ?? g/mL.
You took 50.0 mL of this solution and diluted to 500 mL. So the final concn is
0.11 g/mL x (50 mL/500 mL) = ?? g/mL.
g glucose in 100 mL = ?? g/mL x 100 mL = xx g/100 mL.
