how many grams of glucose were administered to the patient?

Question

A glucose solution is frequently used as an intravenous (IV) solution to supply hydration and/or nutrition. Calculate amounts of glucose provided and volumes used. A patient received 3.25 L of a 0.278 M glucose IV solution. Given that the molecular weight of glucose is 180.156 g/mol, how many grams of glucose were administered to the patient?

Answer 1

3.25 L x 0.278 moles/L x 180.156 g/mol = 162.77 g = 163 g (3 sig. figs.)

Did you include units when you entered your answer? 163 grams is the correct answer.

Answer 2

163 to three significant figures 0.278 Moles/L (M) X 3.25L=0.904 moles x 180.156 grams/mole=162.77 grams or 163 grams to three significant figures.
