Molarity is a unit for expressing the concentration of a solution
Explanation:
Molarity is used to express the concentration of a solution. Also known as molar concentration, molarity is the number of moles of solute (the material dissolved) per liter of solution. It measures the concentration of a solution. The molarity of a solution is calculated by taking the moles of solute and dividing by the liters of solution. Hence, Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution.
Molarity is commonly expressed as molar. Molar also refers to the unit of concentration called molarity, which is equal to the number of moles per liter of a solution. In chemistry, the term most often refers to molar concentration of a solute in a solution. Molar concentration unit also implies the units mol/L or M.

Explanation:
The purpose of this lab was to explore the different types of chemical reactions in this laboratory procedure. The question for this lab is, how does knowing the reactants and products help me classify a chemical reaction. In this experiment, I made observations of the reactants and the products. I used these observations to write the balanced chemical equations and to classify the reaction it made.
