## What is the mole of argon?

To solve this let us find out the molar mass of Argon, it is 39.948 g/mol or roughly **40 g /mol**. It means that one mole of Argon weighs 40g.

## How many moles of Argon are in 100 g of Argon?

Answer: **2.5 moles** of Argon is present.

## How do we find atomic mass?

For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). **By adding together the number of protons and neutrons and multiplying by 1 amu**, you can calculate the mass of the atom.

## 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**.

## How many moles are in 15 grams of lithium?

The numeric value of this constant is 6.022×1023. – Now, we can find the number of moles by the formula of moles that is given mass of the substance divided by the molar mass of the substance. – Hence, we can conclude that there are **17.28×1023 moles** in 15 grams of lithium.

## What is a mole equal to?

A mole is defined as **6.02214076 × 10 ^{23} of some chemical** unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
