Converting between Metric Units

The Metric System is based on the fundamental units of measure for length, volume, and mass. Length: meter (m) Volume: liter (L) Mass : gram (g) Base units in the Metric System can be converted into units that are more appropriate for the quantity being measured by adding a prefix to the name of the…

Limiting Reagents & Moles

In a Chemistry lab you are asked to figure out how many moles of Al2O3 can be produced from the reaction of 10.0g of Al and 19.0g of O3.

A short series of basic aqueous reactions

When two different aqueous solutions meet, it is important to know what happens. You could get a solid, a gas, or no reaction at all. This tutorial will provide a series of questions to test your knowledge, and assumes that you have at least a basic understanding of the fundamentals of aqueous chemistry.

Stoichiometry Helps Chemistry

EASY STOICHIOMETRY CHEMISTRY What is Stoichiometry? Stoichiometry involves calculations with understanding of basic concepts of chemical equations. It is a mathematical part of balanced chemical equations and reactant-product mole ratio. If mass of one of the reactants or products in a chemical reaction is given, mass of another reactant or product can be calculated using…
