Commercially available aqueous solutions of glucose (C6H12O6) are typically labeled as having a concentration of 5%(w/v). This means that a 100 mL sample of the solution contains 5 g of C6H12O6.

a. How many moles of glucose are in a 4.16 mL sample of a 5%(w/v) solution? Hint: first calculate the mass of glucose in the 4.16 mL sample given that a 100 mL sample contains 5 g of glucose; then convert mass to grams.
NG 2

b. If you need 0.0199 moles of glucose for an experiment, how many mL of the 5%(w/v) glucose solution would you dispense?
