# How many particles are in 2 moles of water?

Contents

Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water. Double that for 2 moles, and there are 24.088 x 10^23 hydrogen atoms in one mole of water.

## How many atoms are in 2 moles of H2O?

Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.

## How many particles are in 2 moles?

Deriving and Applying the Equation N = n × N A

n (amount of substance in moles) × N (number of particles)
1 mol × 6.022 × 1023 particles
2 mol × 1.204 × 1024 particles
10 mol × 6.022 × 1024 particles
0.5 mol × 3.011 × 1023 particles

## What is the mass of 2 mole of water?

If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams.

## What is the mass of 2 moles of H2O?

One mole of H2O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol.

## How many atoms are in a mole?

Avogadro’s Number and the Mole. The mole is represented by Avogadro’s number, which is 6.022×1023 atoms or molecules per mol.

## What is the mole of H2O?

Molar mass H2O = (2×atomic mass H) + (1×atomic mass O) = (2×1.00794) + (1×15.9994) = 18.02 • 1 H2O molecule has a mass of 18.02 amu. 1 mole of H2O molecules has a mass of 18.02 grams.

## How did Avogadro find the mole?

The term “Avogadro’s number” was first used by French physicist Jean Baptiste Perrin. … If you divide the charge on a mole of electrons by the charge on a single electron you obtain a value of Avogadro’s number of 6.02214154 x 1023 particles per mole.

## What name is given to the number of particles in a mole?

What is Avogadro’s number? Avogadro’s number is the number of units in one mole of a substance, or 6.02214076 × 1023. This number is also called the Avogadro constant.

## How much does 1 mole of gold weigh?

A gold atom has an (average) atomic weight of 197.0 amu. That means that a MOLE of gold atoms will have a mass of 197.0 g.

18.01528 g/mol

## What is the mass in gram of 2 mole of water?

Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.
