1. CH3OH (shown below) is soluble in water. Draw molecular level pictures representing: (a) a container with only CH3OH (several molecules) before mixing and (b) after CH3OH is dissolved in water H .. H- C O H H 2. MgCl₂ is an ionic compound that is soluble in water. Draw a molecular level picture that represents after MgCl2 is dissolved in water.

An aqueous solution is 12.0% by mass ammonia, NH3, and has a density of 0.950 g/mL.The molarity of ammonia in the solution is

This question is part two of three. When answering this problem, report the answer with the appropriate number of significant figures. When entering units, use proper abbreviated units with proper capitalization. A solution is prepared by combining 5.92 grams of an unknown non-electrolyte with 240.0 grams of chloroform. The freezing point of the mixture is -64.80 oC, while the freezing point of pure chloroform is -63.50oC. The kf of pure chloroform is 4.68oC/molal. Based on this information, how many moles of solute are present in this solution? What is the molar mass of the solute?  Report both answers in scientific notation with appropriate sig figs.

Vinegar is a solution of acetic acid (the solute) in water (the solvent) with a solution density of 1010 g/L. If vinegar is 0.80 M acetic acid, what is the % by mass concentration of acetic acid in vinegar?
