Part C You need to prepare a 2.40 M solution of sodium hydroxide (molar mass of sodium hydroxide = 40.00 g/mol ), but you only have a 10 mL graduated cylinder and a 25 mL beaker. Complete the following sentences regarding the concentration of the prepared solution. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. • View Available Hint(s) Reset Help greater than 10.0 mL 1. In order to prepare 10.0 mL (0.0100 L) solution of 2.40 M sodium hydroxide, a mass of would be required. exactly 10.0 mL exactly 2.40 M 2. When the solute and a total of 10.0 mL of water are both added into the beaker and stirred until 0.024 g the solute dissolves, the solution volume will be greater than 2.40 M 3. Based on that, the concentration of the prepared solution will be less than 2.40 M. less than 10.0 mL 0.960 g P Pearson
