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 .

How many atoms are in a mole of oxygen?

One mole of oxygen atoms contains 6.02214179×1023 oxygen atoms.

What is the mass of 3 moles of oxygen atoms?

1 Answer. 3 moles of Oxygen atoms weigh 48.00 grams.

How many atoms are in 3 moles of water?

If you have a compound like H2O, then: one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

How many oxygen atoms are in a mole of water?

Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.

How many atoms are 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.

How many atoms are in a mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

How many moles are in 10 grams of NaOH?

The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide. The SI base unit for amount of substance is the mole.

What is a mol equal to?

One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro’s number or Avogadro’s constant. The concept of the mole can be used to convert between mass and number of particles.. Created by Sal Khan.

Is Avogadro’s Number?

Avogadro’s number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 1023. … The units may be electrons, atoms, ions, or molecules, depending on the nature of the substance and the character of the reaction (if any).

What is the smallest unit of matter?

Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.

How much oxygen is in 100 grams of water?

So in 100 g of water 89 g will be of oxygen while 11 g will be of hydrogen.

How many moles are in 50 grams of water?

1 Answer. There are 3 moles of O in 50 g.

How many atoms are in 8 grams of oxygen?

→ 8 g = 0.5 mol. Therefore: Number of atoms = 6.022*10^23 * 0.5 = 3.011 * 10^23 oxygen atoms.
