A student placed 13.5 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 25.0-rm mL sample of this glucose solution was diluted to 0.500 rm L. How many grams of glucose are in 100. rm mL of the final solution?
