## Is the mass of one mole of carbon-12?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. **12.00 g C-12** = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

## What is the mass of mole?

The mole is related to the mass of an element in the following way: one mole of carbon-12 atoms has 6.02214076 × 10^{23} atoms and a mass of **12 grams**. In comparison, one mole of oxygen consists, by definition, of the same number of atoms as carbon-12, but it has a mass of 15.999 grams.

## How many atoms are in a mole of oxygen?

1.4.

For one gram atomic weight of oxygen with atomic weight of 16 grams, one mole of oxygen also contains **6.022 × 10 ^{23} oxygen atoms**.

## What is the formula of mole?

Avogadro’s number is a very important relationship to remember: **1 mole = 6.022×1023 6.022 × 10 23 atoms**, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

## What is formula of mass?

Mass is defined as the amount of matter present in a body. The SI unit of mass is the kilogram (kg). The formula of mass can be written as: **Mass = Density × Volume**.

## What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to **multiply the mole value of the substance by its molar mass**.
