Question

calculate the following:i)the mass of one atom of oxygen. II) the mass of one molecule of O2. III) the mass of one mole of O2. Iv) the mass of one ion of O2. v) the no. of atoms in 1 mole of O2 molecule.

Answer 1

In chemistry, a mole is a quantity unit that stands for the amount of a given substance. Since one mole of any chemical compound always contains 6.022 x 10^23 molecules, you can calculate the number of molecules of any substance if you know its mass and its chemical formula. The number 6.022 x 10^23 is called as the Avogadro constant.

Answer 2

Answer: Well, here is the solution friend

1)The mass of one atom of O=2.65×10^23g

2)The mass of one molecule of O2=13.58×10^23

3)The mass of one mole of O2=36g

4)Hello, frnd Oxygen has only atoms

5)No. of atoms in 1 mole of O2 molecule=36.264484×10^46 atoms

Hope it helps..
