Molarity (M) of the solution has to be determined. Concept introduction: Molality (m): Molality is the number of moles of solute present in one kilogram of solvent. Molality is estimation of moles in relationship with solvent in the solution. Molality (m) = Number of moles of solute 1kg of solvent Molarity (M): Molarity is number of moles of the solute present in the one liter of the solution. Molarity (M) = Number of moles of solute 1 liter of solution Molarity is estimation of moles in the total volume of the solution while molality is estimation of moles in relationship with solvent in the solution.

(a)

Interpretation Introduction

Interpretation:

Molarity (M) of the solution has to be determined.

Concept introduction:

Molality (m): Molality is the number of moles of solute present in one kilogram of solvent. Molality is estimation of moles in relationship with solvent in the solution.

Molality (m) =Number of moles of solute1kg of solvent

Molarity (M): Molarity is number of moles of the solute present in the one liter of the solution.

Molarity (M) = Number of moles of solute1 liter of solution

Molarity is estimation of moles in the total volume of the solution while molality is estimation of moles in relationship with solvent in the solution.

In addition to the separation techniques used in this lab (magnetism, evaporation, and filtering), there are other commonly used separation techniques. Some of these techniques are:Distillation – this process is used to separate components that have significantly different boiling points. The solution is heated and the lower boiling point substance is vaporized first. The vapor can be collected and condensed and the component recovered as a pure liquid. If the temperature of the mixture is then raised, the next higher boiling component will come off and be collected. Eventually only non-volatile components will be left in the original solution.Centrifugation – a centrifuge will separate mixtures based on their mass. The mixture is placed in a centrifuge tube which is then spun at a high speed. Heavier components will settle at the bottom of the tube while lighter components will be at the top. This is the technique used to separate red blood cells from blood plasma.Sieving – this is…
