Physics 1120: Angular Momentum Solutions

The angular momentum of an object moving in a circle is r2mΩ, where r is the radius of rotation. At the centre of the disk r = 0, initially. At the final position, the edge of the disk, r = R. The disk is rotating and thus has an angular momentum by IΩ. Consulting a table of moments of inertia, ...

How to Make Simple Solutions and Dilutions

How to Make Simple Solutions and Dilutions 1. Simple Dilution (Dilution Factor Method based on ratios) A simple dilution is one in which a unit volume of a liquid material of interest is combined with an appropriate volume of a solvent liquid to achieve the desired concentration. The dilution factor is the total number of unit volumes in which your material will be

Molarity, therefore, is a ratio between moles of solute and liters of solution. To prepare laboratory solutions, usually a given volume and molarity are required. To determine molarity, the formula weight or molar mass of the solute is needed. The following exam­ ples illustrate the calculations for preparing solutions.
