"Rubbing alcohol" is a mixture that is 70.% isopropyl alcohol (C3H8O) in water.  The mixture has a density of 0.79 g/mL at 20°C. What is the concentration of the isopropyl alcohol in molarity? The molar mass of isopropyl alcohol is 60.11 g/mol.   a. 11.6 M   b. 13.1 M   c. 9.2 M   d. 30.7 M

Write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H2O).

QUESTION 10 (4b-401-1.53-1) An intern working in a research lab knocks over a beaker containing an important solution. The beaker originally contained 1.50 L of a 1.53 M solution, but after it spilled it only contained 1 L of solution. The intern decides to hide his mistake by refilling the beaker to contain 1.50 L again by adding pure water (not realizing that this will dilute the solution). What is the new concentration of the solution? Show all work and give your answer with three sig figs. Click Save and Submit to save and submit. Click Save All Answers to save all answers.
