# How many moles of O2 are there in 1 20 10/22 oxygen molecules?

Contents

One mole of oxygen contains 6.022 × 1023 molecules. 1.20 × 1022 molecules of oxygen contain = 1.20 × 1022 / 6.022 × 1023 = 0.01099 moles.

## How many moles are in an O2 molecule?

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.

## How many moles of O2 are there in one point?

One mole of oxygen atoms contains 6.02214179×1023 oxygen atoms. Also, one mole of nitrogen atoms contains 6.02214179×1023 nitrogen atoms.

## How many moles are in 22.4 liters of oxygen?

Recall that at STP the volume of 1 mole of any ideal gas will be 22.4 liters. Put another way, 22.4 L = 1 mol. 3 L x 1 mole/22.4 L = 0.134 moles O2 gas.

## How many oxygen molecules are in O2?

Molecular oxygen (O2) is a diatomic molecule that is composed of two oxygen atoms held together by a covalent bond.

## How many molecules are in 23 moles of O2?

The number of molecules of oxygen in 23 moles of oxygen is 1.385 x 1025 molecules of oxygen.

## How many O2 molecules are in 3.45 mole O2?

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 moles of O2 are there in 1.20 into 10/22 oxygen molecules?

One mole of oxygen contains 6.022 × 1023 molecules. 1.20 × 1022 molecules of oxygen contain = 1.20 × 1022 / 6.022 × 1023 = 0.01099 moles. Hence, 1.20 × 1022 molecules of oxygen contain 0.0199 moles of oxygen.

## How many moles are in 10 grams of oxygen?

Hence, there are 0.3125 moles of oxygen are present in 10 g of oxygen gas.

## What is the molar mass of O2?

One mole of a gas at STP occupies a volume of 22.4 liters. So 21 liters of the gas would be 21/22.4 = 0.9375 moles of gas. O2 has an atomic mass of 32 grams per mole. So 32 * 0.9375 = 30 grams.

## What is the mass of 22.4 L of O2 at STP 5 points?

Mass is 32*V/22.4g here V=22.4 and thus mass is 32gram (g=gram)!!!!

## What is the mass of 22.4 l of n2 at STP?

Nitrogen gas is composed of 2 atoms of nitrogen. The atomic weight of nitrogen is 14, so for nitrogen gas, 28 gm/mole. One mole of any ideal gas at STP occupies 22.4 L. Thus, 22.4 L of nitrogen gas weighs 28 gm.

## What is the 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 I calculate moles?

How to find moles?

1. Measure the weight of your substance.
2. Use a periodic table to find its atomic or molecular mass.
3. Divide the weight by the atomic or molecular mass.
4. Check your results with Omni Calculator.

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

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