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.

## How many oxygen atoms are there in 2.0 moles of O2?

1 Answer. There are 6×6.022×1023 atoms in 2.00⋅mol NO2(g) .

## How many moles of O2 are consumed?

Calculate mol H2O by dividing its given mass by is molar mass (18.015 g/mol) . Calculate mol O2 by multiplying mol H2O by the mol ratio between H2O and O2 in the balanced equation, with O2 in the numerator. 4.73 mol O2 must be consumed to produce 68.1 g H2O in the given reaction.

## How many atoms are present in 2 moles of oxygen?

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.

## What is the mass of 1 mole of O2?

Moles of a Substance and the Molecular Weight

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 many moles were consumed in the reaction?

Divide Grams by Grams per Mole

Divide the number of grams of each reactant by the number of grams per mole for that reactant. 50.0 g of Na are used in this reaction, and there are 22.990 g/mol. 50.0 ÷ 22.990 = 2.1749. 2.1749 moles of Na are used in this reaction.

## How many moles can be produced?

For any balanced chemical reaction, whole numbers (coefficients) are used to show the quantities (generally in moles ) of both the reactants and products. For example, when oxygen and hydrogen react to produce water, one mole of oxygen reacts with two moles of hydrogen to produce two moles of water.

## How many moles of water are formed per mole of oxygen?

Assuming that oxygen is our limiting reactant (because it is not otherwise specified), we can find that per one mole of oxygen, we get two moles of water. This means that per four moles of oxygen, we get eight moles of water.

## How many moles are in 16g of oxygen?

Answer. 16 g i equal to 0.5 mole of oxygen molecule. we know in one molecule of oxygen there are 2 atom. Hence in 0.5 mole of oxygen molecule, there are 0.5 * 2 mole of atom of oxygen.

## How many grams are in 6 moles of oxygen?

›› More information from the unit converter

The answer is 15.9994. We assume you are converting between grams Oxygen and mole. You can view more details on each measurement unit: molecular weight of Oxygen or mol The molecular formula for Oxygen is O.

## What is the weight of 2 moles of oxygen gas?

From here, the answer is simple. Just multiply 2 by 31.9988 g because there are two moles of oxygen. So, the answer is 63.9976 g ..

## How many atoms of oxygen is present in 0.5 moles of oxygen?

(ii) 3.011 x 1023 atoms of oxygen.

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

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 the mass of 3 mole of oxygen?

3 moles of Oxygen atoms weigh 48.00 grams.
