How many moles of oxygen atoms is this?

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 4 moles of oxygen atoms?

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 atoms of oxygen are present in 4 moles of oxygen?

For one mole atoms of oxygen mass of \[{\text{N}}{{\text{O}}_2}\] will be \[23{\text{ g}}\] and for 4 moles it will be \[4 \times 23{\text{ g}} = 92{\text{ g}}\]. Hence 4 moles of oxygen atoms are present in 92 g of \[{\text{N}}{{\text{O}}_2}\]. Thus, option B is the correct answer.

How many atoms are in moles?

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.

How many moles of O2 are in 48 g O2?

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

How many moles of oxygen are present in 4.0 g of the gas?

First, we need to calculate the molar mass of oxygen gas. Oxygen gas is O2 . O2 has a molar mass of 32g/mol . ∴ There are 1.25 moles of O2 in 40g of oxygen gas.

How many moles are there in 4 gram of oxygen?

To calculate the number of molecules in 4g of oxygen, we have, Moles of oxygen = 4/32 = 0.125mol, Molecules of oxygen = 0.125 * 6.022 * 1023 = 7.52 * 1022.

How many atoms are in this Formula 4 O2?

Thus 4 grams of oxygen has 1.5055 x 10^23 atoms.
