The mass of 1 mole of a substance is equal to its relative atomic or molecular mass in grams.

## Is grams per mole the same as moles?

The mass of one mole of atoms of a pure element in grams is equivalent to the atomic mass of that element in atomic mass units (amu) or in grams per mole (g/mol). Although mass can be expressed as both amu and g/mol, g/mol is the most useful system of units for laboratory chemistry.

## Why is a mole 6.02 x10 23?

Originally, a mole was the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. That number of particles is Avogadro’s Number, which is roughly 6.02×10^{23}.

## How much is in a mole?

The mole, abbreviated mol, is an SI unit which measures the number of particles in a specific substance. One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules.

## Why is a mole 6.022 x10 23 Quora?

The answer is twice Avogadro’s number. A mole contains molecules, but each molecule of chlorine gas contains two atoms. A mole is one gram molecular weight. So it counts molecules, not atoms.

## Why do we use grams instead of moles?

You need to convert using the weight. Grams depends on the molecule itself, oxygen weighs more than hydrogen. But using moles gets rid of the mass concern, because a mole represents a specific amount of molecules, independant of weight.

## How do I calculate moles?

How to find moles?

- Measure the weight of your substance.
- Use a periodic table to find its atomic or molecular mass.
- Divide the weight by the atomic or molecular mass.
- Check your results with Omni Calculator.

## How do you find moles from molarity?

To calculate the number of moles in a solution given the molarity, we multiply the molarity by total volume of the solution in liters.

## How do you find moles from grams and volume?

There are two steps:

- Multiply the volume by the density to get the mass.
- Divide the mass by the molar mass to get the number of moles.

## How do you find moles from grams and liters?

Converting from moles to mass (grams): Multiply your initial mole value by the molar mass of the compound as determined by the periodic table. Converting from volume (liters) to moles: Divide your initial volume by the molar volume constant, 22.4 L.
