1. Glucose (C6H12O6, M= 180.16 g/mol) solutions are commercially available. A concentrated sample of an aqueous glucose solution has a density of 1.25 g/mL and contains 55.0 % glucose by mass at 20 °C a) What is the molarity of this glucose solution? b) What is the molality of this solution? c) What is the mole fraction of glucose in this solution?
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...
What is the molarity of a 14.5% by mass glucose (C6H12O6) solution? (The density of the solution is 1.03 g/mL.)
A solution is prepared by dissolving 28.4 g of glucose (C6H12O6) in 1.00 x 102 mL of acetone (C3H6O) at 25 °C. The final volume of the solution is 118 mL. The density of glucose and acetone are 1.54 g/mL and 0.785 g/mL, respectively. Calculate the following quantities: a.) Molarity b.) Molality c.) Mass Percent d.) Mole Fraction

Pour 2.5 mL of the 1M glucose (C6H12O6) solution from the flask into the 100 mL volumetric flask. Use the “dilution equation” to determine the volume in mL for the required 0.025M solution, given that the original solution is 1M and you used 2.5 mL Fill the volumetric flask to the 100 mL mark with distilled water. Note: The flask already contains a volume of 2.5 mL. 1. Compute the volume of the diluted 0.025 M solution. 2. What volume...
