Description

This free online Moles Calculation course introduces you to the concept of relative isotopic and atomic masses and how to use the relative atomic mass in calculating the relative molecular and formula masses. It also teaches you to deduce the empirical and molecular formulas, balancing chemical equations, and how to write ionic equations, simplification of precipitation equations, and how to calculate the formal charges.The course then moves on to give you a clear explanation of the units used to describe the amount of a substance, and how to convert between them. The course also discusses formulas used to deduce the moles of a reaction, volumes, concentrations, percentage composition by mass, and Avogadro’s number. You will also learn acid/base titrations and how to use the information of one solution to deduce the concentration of another solution using titration.

The key points covered in the course are: the relative atomic mass is the weighted average mass of atoms of an element,the relative molecular mass is the sum of the relative atomic masses of elements in a compound and the relative isotopic mass of a substance can be calculated using a mass spectrometer. The mole is the IS unit used to describe the amount of a substance, one mole of a substance contains a number of particles equal to the same number found in 12 grams of carbon-12.The molecular formula is a set of symbols used to describe the total number of atoms in a compound. The simplification of the molecular formula is called the empirical formula.The mole can be used to calculate: reacting masses in grams, volumes of gases in cm-3, volumes and concentration of solutions.The stoichiometry of a reaction is the molecular ratio of reactants and products; it can be calculated using the volumes, concentrations, and masses of the reactants and products.

The basic concepts of describing a chemical reaction and the stoichiometry of a reaction are essential skills for any student who is enrolled in any science major. This free online course will help you understand and practice your knowledge of the included topics using examples, and exercises. Enroll now and start learning.
