1 If you want to plug in more than one USB accessory at onceâfor example a mouse and a printerâyou can use a USB hub (sold separately) with its own power supply. 2  The power supply thatâs included with Surface Pro models has a USB charging port you can use to power other USB devices while youâre charging your Surface.
Different types of titrations such as acid-base titrations and oxidation-reduction titrations have been utilized in chemical analyses. In this experiment an acid-base titration will be used to determine the molar concentration of a sodium hydroxide (NaOH) solution.Acid-base titrations are also called neutralization titrations because the acid reacts with the base to produce salt and water.ifferent types of titrations such as acid-base titrations and oxidation-reduction titrations have been utilized in chemical analyses.

1 Determine the moles of unknown (the solute) from the molality of the solution and the mass of solvent (in kilograms) used to make the solution. 2  Determine the molar mass from the mass of the unknown and the number of moles of unknown. Determine the molar concentration of the unknown in the solution from the observed osmotic pressure. 2  Determine the moles of unknown (the solute) from the molarity of the solution and the volume (in liters) of the solution. 3  Determine the molar mass from the mass of the unknown and the number of moles of unknown.
