3 moles of Oxygen atoms weigh 48.00 grams.

## How many atoms will be there in 3 moles of o2?

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.

## What is the mass of 1 moles of oxygen?

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. 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.

## What is the mass of three oxygen atoms?

O3 is the formula for ozone. It has three oxygen atoms. The ozone protects living organisms from ultraviolet rays. The molar mass of ozone is 47.998g.

## What is the mass of 2 oxygen moles?

per mole of oxygen. 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 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 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 grams are there in 3.5 moles of oxygen?

The atomic mass of oxygen is approximately 16 grams, however o2 would make it 32 grams. Then one would multiply 32 by 3.5 moles which would give you 112 grams per 3.5 moles. So,3.5 moles of oxygen has mass=3.5×16=56grams.

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

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

## What is the mass of 1 mole?

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

## How many moles of so2 have the same mass as 3 moles of oxygen?

Conclusion: 0.75 moles of have same mass as 3 moles of oxygen.

## How many moles are in oxygen?

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 is the mass of 3 moles of calcium atoms?

Therefore, $mass = 332.9g$ .

## What is the mass of 3 moles of neon?

We know, molar mass of neon ( mass of one mole of neon) = 20 gram. Hence, mass of 3 mole of neon = 3 × 20 = 60 gram.

## What is the mass of 4 moles of oxygen atom?

Explanation: 4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = 128 g. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.

## How many moles of oxygen are produced when 3 moles of kclo3 decompose completely?

2KClO3 –> 2KCl + 3O2

(3/2)*(3.0) moles O_{2}, or 4.5 moles of O_{2}. Kaitlyn G.
