You are required to prepare a 0.25 M solution of glucose (f.w. 180 g/mole) in your rotation lab. Your mentor forgot to indicate how much, so you assume she wants a whole liter of it. How many grams of glucose do you need? How is the volume adjusted? a. Place 90 g of glucose in an Erlenmeyer flask or beaker and add 1 L of tap water. b. Place 90 g of glucose in a graduated cylinder or a volumetric flask and fill with deionized water (diH2O) until the bottom of the meniscus is on the 1-L mark. c. Place 45 of glucose in an Erlenmeyer flask and add 1 L of tap water. d. Place 45 g of glucose in a graduated cylinder or preferably a volumetric flask and fill with deionized water (diH2O) until the bottom of the meniscus is on the 1-L mark.
