A student placed 19.0 of glucose (C6H12O6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100.- mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 45.0- sample of this glucose solution was diluted to 0.500 . How many grams of glucose are in 100. of the final solution?
