What is being calculated when the moles of a solute in a solution is divided by the molarity of the solute in the solution?
1) The moles of solute in the solution
2) The moles of solution
3) The milliliters of volume in the solution
4) The molarity of the solute in the solution
5) The liters of solute in the solution
6) The volume of the solution in liters
7) The milliliters of water in the solution
8) The moles of water in the solution
Describe the procedure you will use to determine those cation/anion pairs that produce precipitates. Make sure you include all equipment and amounts of materials you expect to use
titrated Acetic Acid with Sodium Hydroxide. The endpoint measured 27.9 mL. The NaOH concentration was figured out by titration of a primary standard KHP. The resulted concentration was ~.2651 M NaOH
One liter of a gas has a pressure of 150.00 kPa at 25.0°C. If the pressure increases to 600.0 kPa and the temperature to 100.0°C, what would be the new volume of the gas?
The molar mass of cellulose is approximately 6.0 x 105 g/mol and the molar mass of a soluble starch is on the order of 4.0 x 103 g/mol. The monomer unit in both of these molecules has the emperical formula C6H10O5
