Molarity

This past week in class, we have been focusing on morality. The equation to find a substances molarity, divide the moles of the solute by the liters of the solution. Although, volume is temperature dependent, so molarity can change with temperature. Here is a website I found explaining the basics of calculating molarity: Finding molarity

We also learned about the concentration of ions in a solution and the Van't Hoff factor. This is the number of ions that a compound will contribute to a solution (i). The Van't Hoff factor for covalent compounds is always 1. Here is another website I found, this one explaining the factor: Van't Hoff factor.

Lastly, we learned about dilutions. To find molarity of volume in a dilution, use the formula M1V1= M2V2. In a dilution, the high concentration substance is the stock and the low concentration substance is the making. An aliquot is a small amount of a starting solution. Here is another website, this one explaining dilutions and their equation: Dilutions
