You are asked to prepare a 1.000 L solution of 4.5 M C6H12O6 (glucose; molar mass = 180.16 g/mol) in a lab by dissolving 811.0 g of glucose in water. Consider the following two scenarios in whic you commit a user error while preparing this solution. Prepared in a volumetric flask 1.000 L Assumed volume Volumetric Added water 2.0 cm above the line, which corresponds to 8.2 mL (0.0082 L) additional error solution volume Preparation details You add the glucose to a volumetric flask and then add water until it dissolves. The water bottle you are using has a worn tip, and you inadvertently add too much water such that the meniscus is above the line. The diameter of the neck of the volumetric flask is 2.29 cm. 811.0 g glucose You decide to evaluate and compare the errors you made while preparing the solutions using the different methods. Calculate the actual concentrations of the intended 4.5 M glucose solutions prepared by each method based on their actual final volumes. Express the concentrations in molarity to two decimal places. Make certain each field is complete before submitting your answer. ► View Available Hint(s) Concentration: M 811.0 g glucose Prepared in a beaker 1.000 L 811.0 g takes up 526 mL of space rather than 500 mL of space You prepare the solution by adding glucose to a large beaker and approximated the volume of the glucose to be 500 mL. Therefore, you add 500. mL of water to the 526 mL in the beaker using a graduated cylinder. ||||||| Concentration: C ? |||| M
