Explanation: A mole of anything contains 6.022×1023 individual items of that something. You have 3 moles, so there are 3×6.022×1023 oxygen molecules .

## What is 3 moles O2?

Feb 28, 2018. 3 moles of Oxygen atoms weigh 48.00 grams.

## How many molecules of oxygen are in a mole?

One mole of oxygen gas, which has the formula O_{2}, has a mass of 32 g and contains 6.02 X 10^{23} molecules of oxygen but 12.04 X 10^{23} (2 X 6.02 X 10^{23}) atoms, because each molecule of oxygen contains two oxygen atoms.

## How many O2 molecules are there in 3 moles of O2?

According to Avagadro, there are 6.022 × 10^23 molecules in 1 mole of any compound, irrespective of elements or the mass of compound. Thus in 3 moles of O2, there are 3 ×6.022× 10^23 molecules of O2, that is, 18.066×10^23 molecules of O2. Thanks!

## How many oxygen atoms are there in 3 moles of co2?

There are 3.6132 x 1024 oxygen atoms in exactly three moles of carbon dioxide.

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

3 mol Na × (6.022×10^23 atoms Na/1mol Na) = 1.807×10^24 atoms Na.

## How much is 3 moles?

One mole of any substance is equal to its molar mass. 3 moles of water has a mass of 30g. similarly 1 mole of water is equivalent to molecular mass of water x 3 that is 18×3=54 gram. It would constitute 3N molecules of water.

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

Explanation: 1 mole of O₂ contains 6.022 × 10²³ atoms. Thus, 3 moles O₂ would contain 3 × 6.022 × 10²³ atoms. Therefore, 3 moles of O₂ contain 18.066 × 10²³ atoms.

## How many molecules are in 1 mole of any gas?

A mole is the quantity of a substance such that the mass is equal to the molecular weight in grams. For any perfect gas 1 mole occupies a volume of 22.4 liters at 0°C, 101.325 kPa. A mole contains the Avogadro’s number of molecules, 6.023 × 10^{23}.
