How to determine the mass percentage of each element in a chemical compound from its chemical formula is also outlined. This section includes worked examples, sample problems, and a glossary. Define the unit of the mole and illustrate its application as a tool to convert among macroscopic and submicroscopic quantities.
One mole of a substance contains approximately 6.022 × 10 23 particles, a number known as Avogadro's number. The unit of molarity, M or mol/L, simply tells you how many moles of solute are dissolved in one liter of solution. For example, a 1 M (1 mol/L) solution contains 1 mole of solute in every liter of solution.
We use the unit to make calculations based on balanced chemical equations. We use the stoichiometry (fancy way of saying mole ratios in an equation) to make predictions about how much product will be made or reactant needed if we know one mole amount in a reaction.
Use a balanced chemical equation to determine molar relationships between substances. Previously, you learned to balance chemical equations by comparing the numbers of each type of atom in the reactants and products.
Use this mole calculator to find how many moles, molecular weight, and molar mass are required for your experimental measurements. What Is A Mole?
