Finding the Volume of an Irregular 3D Solid: Additive Property of Volume
In this video, the teacher explains how to find the volume of an irregular 3D solid by recognizing that volume is additive. They demonstrate this concept by breaking down the solid into two rectangular prisms and finding the volume of each.

Solubility Product Constant (Ksp)
We've learned that some ionic solids are totally water insoluble, but in fact this is a slight oversimplification. Even such solids will dissolve to some minuscule degree, and we can measure this, and do calculations with it. Let's learn...
