## What is the 1 mole of oxygen?

The mass of oxygen equal to one mole of oxygen is **15.998 grams** and the mass of one mole of hydrogen is 1.008 g.

## How do you calculate 1 mole of oxygen?

Calculate the number of oxygen atoms in 1 mole of O2. Solution — 1 molecule of O2 = 2 oxygen atoms So, 1 mole of O2 = 2 mole oxygen atoms = 2 × 6.022 × 1023 = **12.044 ×1023 oxygen atoms**.

## What is the 1 mole is equal to?

One mole of a substance is equal to **6.022 × 10²³ units** of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro’s number or Avogadro’s constant.

## How do you convert to moles?

A substance’s molar mass is calculated by **multiplying its relative atomic mass by the molar mass constant** (1 g/mol). The molar mass constant can be used to convert mass to moles. By multiplying a given mass by the molar mass, the amount of moles of the substance can be calculated.

## How do you find the mole?

So in order to calculate the number of moles of any substance present in the sample, we simply **divide the given weight of the substance by its molar mass**. Where ‘n’ is the number of moles, ‘m’ is the given mass and ‘M’ is the molar mass.

## Why is a mole 6.022 x10 23?

The mole (abbreviated mol) is the SI measure of quantity of a “chemical entity,” such as atoms, electrons, or protons. It is defined as the amount of a substance that contains as many particles as there are atoms in 12 grams of pure carbon-12. So, 1 mol contains 6.022×10^{23}**elementary entities of the substance**.

## How many times is 1 mole of oxygen atom is heavier than 1 mole of hydrogen atom?

Therefore, it can be said that 1 mole of oxygen atom is nearly **16 times** heavier than 1 mole of hydrogen atom.

## What is 1 mole in grams?

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight **18.015 grams**.
