Chemistry from University of Kentucky. This course is designed to cover subjects in advanced high school chemistry courses, correlating to the standard topics as established by the American Chemical Society.
This page describes, with fully worked out examples, how to calculate the volume of gas formed from a given masses of reactants. You need to know the formula connecting moles, mass and formula mass AND know how to use the molar volume in these calculation methods.

What is Molar Mass? Molar mass is literally the mass of one mole of a substance. We saw in a previous lesson on atomic mass that the periodic table provides us with the average atomic mass of elements.
Molar Mass Calculator Tool Determine the Molar mass and Percent mass composition of a linear chemical formula. Enter a valid molecular formula and press the calculate button to determine the correct molar mass.
Definitions of solution, solute, and solvent. How molarity is used to quantify the concentration of solute, and comcalculations related to molarity.
Online molarity calculator from Sigma-Aldrich.com makes calculating molarity and normality for common acid and base stock solutions easy with most common values pre-populated.
In chemistry, the molar mass M is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance. The base SI unit for molar mass is kg/mol.
How to Calculate Mass. Mass means how much matter there is in something. Matter is something you can physically touch. Generally, mass is related to size but not always.
How to Calculate Percent Yield in Chemistry. In chemistry, the theoretical yield is the maximum amount of product a chemical reaction could create based on chemical equations.
