## How many moles are in O2?

**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.

## What number of moles of 02 is needed to produce 14.2 grams of P4O10?

Hence, **0.25 mole** of O2 is needed to produce 14.2 grams of P4O10 from P.

## How do you calculate the number of moles needed?

Determine the moles of product produced **by dividing the grams of product by the grams per mole of product**. You now have calculated the number of moles of every compound used in this reaction. 41.304 g of NaCl ÷ 58.243 g/mol = 0.70917 moles of NaCl.

## How many oxygen atoms are in 4.0 moles of O2?

Oxygen gas (O2) is made up of 2 atoms of oxygen. Since oxygen has an atomic mass of 16 g/mole, the molar mass of oxygen gas (O2) is 2 x 16 g/mole = 32 g/mole. Since 1 mole of oxygen is equivalent to 32 g, 4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = **128 g**.

## How many moles are in 16g of O2?

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 moles of O2 are needed to produce 75 grams of P4O10 from P4O10 284 g mol?

(75g)/(284g. mole) = 0.2641 moles [the g cancles and moles moves to the top]. Rounded to 2 significant figures (since 75 is only 2 significant figures), the number of moles of P4O10 is 0.26. The equations says we need **5 moles of** O2 for every mole of P4O10.

## What volume of O2 is required?

What is the volume of O2 required at STP for the oxidation? ⇒ **22.4 L** of O2 is required for the oxidation of 22.4 L of SO2.

## How many grams of calcium nitrate CA No 3 2 contains 24 grams of oxygen atoms?

Question: Question: How many grams of calcium nitrate, Ca(NO3)2, contains 24 grams of oxygen atoms? Answer: **41 gramsHelp**: please show me step by step on how to arrive at answer above. thanks.

## How many moles of O2 can be produced from 12 moles KClO3?

How many moles of O2 can be produced by letting 12.00 moles of KClO3 react? The KClO3 / O2 molar ratio is 2/3. 2 mol KClO3 / 3 mol. O2 = 12.00 mol KClO3 / x = **18.00 mol**.

## What is the mole formula?

Avogadro’s number is a very important relationship to remember: **1 mole = 6.022×1023 6.022 × 10 23 atoms**, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

## How many moles of O2 are needed to produce 12 moles?

To produce 12 moles of water **6 moles** of oxygen gas are needed.

## How many moles of O2 are needed to produce 4 moles H2O?

So, the 4 moles of hydrogen reacts with **2 moles** of oxygen, to give 4 moles of water.

## How many moles of O2 are needed to completely react with 4.0 moles C2H6O?

Thus we can write the conversion factor, 4.0 moles of C2H6O will react with = 4.0 mole of C2H6O = **12 mole** of O2Thus 12 moles of O2 are needed to completely react with 4.0 moles of C2H6O.
