A student placed 11.0 g of glucose (\rm C_6H_{12}O_6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100.-\rm mL mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 60.0-\rm mL sample of this glucose solution was diluted to 0.500 \rm L. How many grams of glucose are in 100 mL of the final solution?
