## How many atoms will be there in 3 moles of Fe?

Explanation: One mole of anything is 6.022×1023 everythings, including atoms. Multiply the moles Fe by 6.022×1023 atoms/mol. 3.77mol Fe ×6.022×1023atoms Fe1mol Fe =**2.27×1024 atoms Fe** rounded to three significant figures.

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

Explanation: The atomic mass of iron (Fe) is 55.85 amu. The atomic mass of radium (Ra) is 226 amu. One mole of atoms of any element contains **6.022 X 1023 atoms**, regardless of the type of element.

## How many atoms are there in 2 mol of Fe iron?

There are **two atoms** in 2 Fe, more correctly written as 2Fe or Fe2. Both atoms are from the same element, iron.

## How many atoms are in 3 moles of hydrogen?

Therefore, 3 moles of hydrogen gas contains **2 x 3 x 6.022 x 10^23 hydrogen atoms**, or 3.6132 x 10^24.

## How many atoms are there in sulfur?

There are **6.022 x 1023 atoms** of sulfur in one mole of sulfur dioxide.

## How many atoms are present in iron?

Explanation: And thus is we have a mole of iron, we have Avogadro’s number , i.e. **6.022×1023 individual IRON ATOMS**……….and this quantity represents a mass of ……….. ??????

## How many atoms are in 1 mole of barium?

The question specified molar quantities, and the mole is just another number, admittedly a very large number, i.e. NA = 6.022×1023 mol−1 . So in 1 mole of BaCl2 , there are **3 × NA barium** and chlorine atoms, where NA is Avogadro’s number, 6.022×1023 .

## How many atoms are in an element?

An atom is an element. The two words are synonymous, so if you’re looking for the number of atoms in an element, the answer is always **one**, and only one.
