## The Mole Relationship to Carbon

Experiments have determined that in 12 g of carbon there are 6.02 x 10²³ atoms. 1 mole is defined as the number of atoms in 12 g of carbon. In other words, 1 mole of carbon contains 6.02 x 10²³ Read More …

## The Mole Concept

A mole of any substance contains a fixed and very large number of particles, known as Avogadro’s constant. Avogadro’s constant is approximately equal to 6.02 x 10²³ particles, which can be tiny particles such as atoms or molecules.

## What is Molecular Mass?

How to calculate molecular mass? Determine the formula of the compound Use the periodic table, determine the atomic mass of each element present in the formula Multiply the atomic mass of each element by the number of atoms Finally, add Read More …

## How to calculate the number of moles

To calculate the molar mass of a substance, you must use the periodic table. Look for the atomic mass of each element present in the compound. Then use a table such as the one below to calculate the the sum of the atomic masses of the compound’s constituent atoms.

## Molar Mass

Molar mass is the weight in grams of one mole of a chemical substance. How to calculate the molar mass of a single element (eg.hydrogen)? The molar mass for an element is the sum of atomic masses, expressed as g/mol. Read More …
