Part A

In the PhET simulation, select the solute in the dropdown menuunder the beaker. The ionic formula of the solute will display onthe beaker. You can click the box adjacent to Showvalues to display the concentration of each solution. Bysetting the Solution Volume slider bar to theminimum and the Solute Amount slider bar to thetop, you can maximize the number of saturated solutions youcreate.

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

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

Part C

A sucrose solution is prepared to a final concentration of 0.250M . 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 ofsolute is included in the density of the solution. Express theconcentrations in grams per liter, molality, and mass percent tothree significant figures separated by commas.

part D

Suppose 217.7 mg of PbCl2 was added to 15.0 mL of water in aflask, and the solution was allowed to reach equilibrium at 20.0oC. Some solute remained at the bottom of the flask afterequilibrium, and the solution was filtered to collect the remainingPbCl2, which had a mass of 60.8 mg . What is the solubility ofPbCl2 (in g/L)?

Express the concentration in grams per liter to threesignificant figures.
