Answer: Al2O3: 3 moles of oxygen are present in 1 mole of Al2O3.

What is the mass of 0.1 mole of oxygen atoms?

Mass of 0.1 mole of oxygen is = 16 * 0.1 =1.6 g.

How many atoms are in 1 mole of iodine?

One mole (abbreviated mol) is 6.022 × 1023 of the microscopic particles which make up the substance in question. Thus 6.022 × 1023 I atoms is referred to as 1 mol I. The 7 × 1017 atoms of iodine in the RDA we have been discussing would be (7 × 1017)/(6.022 × 1023) mol Br, or 0.0000012 mol iodine.

What is the mass of .2 mole of oxygen atoms?

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

What is a 1 mole?

A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

What is the mass of exactly 1 mole of each of the compounds?

Skill 3-1 Calculate the molecular mass of a compound as the sum of the atomic masses of its elements. So, one mole of water (6.022 x 10 23 molecules) has a mass of 18.02 g. One mol of NaCl (6.02 x1023 formulas) has a mass of 58.44 g.

How much 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).
