You are asked to prepare a 1.000 L solution of 4.5 M you commit a user error while preparing this solution. Assumed volume Volumetric error Preparation details Added water 2.0 cm above the line, which corresponds to 8.2 mL (0.0082 L) additional solution volume 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 Prepared in a beaker Prepared in a volumetric flask 1.000 L 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 Concentration: 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…

The molarity of a solution is 0.0200 M or mol/L. Its molar mass is 345.32 g/mol. If you have 50.0 mL of this solution, how many micrograms are contained in it? Hint: You have four conversion factors. 0.0200 moles = 1 liter 345.32 grams = 1 mole 106 micrograms = 1 gram 1000 milliliters = 1 liter Group of answer choices 3.95 x 10^5 micrograms 0.00632 micrograms 5.79 x 10^4 micrograms 1.58 x 10^-4 micrograms
