Part A

In the PhET simulation, select the solute in the dropdown menu under the beaker. The ionic formula of the solute will display on the beaker. You can click the box adjacent to Show values to display the concentration of each solution. By setting the Solution Volume slider bar to the minimum and the Solute Amount slider bar to the top, you can maximize the number of saturated solutions you create.

List the following compounds in order of increasing concentration for their saturated solutions.

Rank from lowest to highest. To rank items as equivalent, overlap them. Gold(III) Chloride, Colbalt(II) Nitrate, Potassium Permaganate, Copper(II) Sulfate

Part C

A sucrose solution is prepared to a final concentration of 0.250 M . Convert this value into terms of g/L, molality, and mass % (molecular weight, MWsucrose = 342.296 g/mol ; density, ρsol′n = 1.02 g/mL ; mass of water, mwat = 934.4 g ). Note that the mass of solute is included in the density of the solution. Express the concentrations in grams per liter, molality, and mass percent to three significant figures separated by commas.

part D

Suppose 217.7 mg of PbCl2 was added to 15.0 mL of water in a flask, and the solution was allowed to reach equilibrium at 20.0 oC. Some solute remained at the bottom of the flask after equilibrium, and the solution was filtered to collect the remaining PbCl2, which had a mass of 60.8 mg . What is the solubility of PbCl2 (in g/L)?

Express the concentration in grams per liter to three significant figures.
