## What is the mole equation?

The molar mass of a substance is the mass of one mole of that substance. It is equal to: the relative atomic mass or A r in grams for atoms and metals. the relative formula mass or M r in grams for molecules and compounds.

Molar mass.

Substance Oxygen O 2 M r = 2 × 16.0 = 32.0 32.0

## What is mole explain?

A mole corresponds to the mass of a substance that contains 6.023 x 1023 particles of the substance. The mole is the SI unit for the amount of a substance. Its symbol is mol. By definition: 1 mol of carbon-12 has a mass of 12 grams and contains 6.022140857 x 1023 of carbon atoms (to 10 significant figures). Examples.

## How do you calculate moles produced?

Determine the moles of product produced by dividing the grams of product by the grams per mole of product. You now have calculated the number of moles of every compound used in this reaction.

## Why mole concept is important?

Explanation: THE mole is important because it allows chemist to work with a subatomic world with macro world units and amount. Atoms molecules and formula units are very small and very difficult to work with usually. However the mole allows a chemist to work with amount large enough to use.

## What is mole concept and molar mass?

Related to the concept of moles, the molar mass of a substance refers to the total mass of one mole of a substance (i.e. molar mass = mass of one mole which is equal to 6.02214076×1023 number of particles of that substance ). … So numerically, one molar mass = mass of (6.02214076×1023 * Atomic mass of that element).

## What is a mole chemistry BBC Bitesize?

The mole is the unit for amount of substance. It is abbreviated to mol. 1 mol is the amount of substance that contains the same number of particles as there are atoms in 12.0 g of carbon-12. Since atoms are so very small and have very little mass , the number of atoms in 12.0 g of carbon-12 is huge.

## What does n m/m mean?

n = m/M n is the amount of substance, in moles, mol. m is the mass of the substance, in grams, g. M is the molar mass of the substance (the mass of one mole of the substance) in g mol-1. Molar masses: These. will be given in.
