One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

## Is oxygen a mole?

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. If we total up the gram amounts of each element in the water molecule = 15.998g/mol + 2(1.008g/mol) we get the molar mass of water = 18.014g/mol.

## Is 2 moles O2?

From here, the answer is simple. Just multiply 2 by 31.9988 g because there are two moles of oxygen.

## What is the mole weight of O2?

An mole of oxygen molecules, O=O , has a mass of 32.00⋅g .

## What is a mole of a substance?

The mole is the amount of substance containing the same number of molecules (or atoms or radicals or ions or electrons) as there are atoms in exactly 12 g of ^{12}C. As if simply stating the term amount of substance clears the matter up.

## What is the mole based on?

Like all units, a mole has to be defined or else based on something reproducible. The present definition of the mole is defined, but it used to be based on the number of atoms in a sample of the isotope carbon-12. Today, a mole is Avogadro’s number of particles, which is exactly 6.02214076×10^{23}.

## Is O2 1 mol or 2 moles?

O might also mean oxygen as the element without specifying its chemical form; O2 can only mean dioxygen gas. Anyway, 1 mole of oxygen gas contains 2 mole of oxygen atoms. It is the same as 1 dozen pairs of shoes and 2 dozen shoes. Mole is a number, like dozen.

## How many moles of oxygen are in O2?

A mole of O2 molecules has 6.023E23 molecules, and each molecule is made up is two atoms of oxygen. That means that there are two moles of oxygen atoms in a mole of O2, or 1.2046E24 of them.

## What is a mole of CO2?

The molecular mass of carbon dioxide is 44.01amu. … One mole of carbon dioxide molecules has a mass of 44.01g, while one mole of sodium sulfide formula units has a mass of 78.04g. The molar masses are 44.01g/mol and 78.04g/mol respectively.

## How many moles of O2 are in 48 g O2?

48 g of individual oxygen atoms = 3 moles of oxygen atoms.

## What is the mole mole ratio of kclo3 O2?

From looking at our balanced equation, we know that 2 moles of potassium chlorate produces 3 moles of oxygen, or O2 . So, our mole ratio of potassium chlorate to oxygen is 2:3 .

## Is O2 16 or 32?

O_{2} is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O_{2} molecule = 2 × 16 = 32 amu.

## Is oxygen a diatomic?

Diatomic molecules contain two atoms that are chemically bonded. If the two atoms are identical, as in, for example, the oxygen molecule (O_{2}), they compose a homonuclear diatomic molecule, while if the atoms are different, as in the carbon monoxide molecule (CO), they make up…
