can be used as a standard solution for checking the concentration of a solution containing sulphuric acid, 8.7 cm' of sulphuric acid. Find the concentration of the sulphuric acid in both mol dm3 and g dm³. In a particular experiment 10,0 cm³ of a 0.50 mol dm³ solution of sodium ethanedioate was found to react with Q2. Sodium ethanedioate, Na;C¿O4, can be made into a solution of an exact and reliable concentration and so London ndon A.C.1.2
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.
