A student placed 19.0 g 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 m L mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 30.0 mL m L sample of this glucose solution was diluted to 0.500 L. How many grams of glucose are in 100. mL m L of the final solution? Express your answer to three significant figures and include the appropriate units.
