Question

what mass of co2 contain 8 moles of O atoms

Answer 1

Explanation:

8 Moles of Oxygen

44 × 4 = 176 Grams

Therefore 132 grams of CO ² contains= 132 / 44 x 2- moles of oxygen-atom= 6 moles of oxygen-atom.

One mole of atoms of oxygen has a mass of 16 g, as 16 is the atomic weight of oxygen, and contains 6.02 X 1023 atoms of oxygen.

A mole of oxygen molecules contains 2 moles of oxygen atoms. For elements that exist as molecules, it is best to explicitly state whether molecules or atoms are meant. Thus "1 mole of oxygen molecules" means 6.022 x 1023 O2 molecules, or 2 x 6.022 x 1023 O atoms; "1 mole of oxygen atoms" means 6.022 x 1023 O atoms.

A mole of CO2 molecules (we usually just say “a mole of CO2”) has one mole of carbon atoms and two moles of oxygen atoms. The atom ratio and the mole ratio of the elements are identical!

Answer 2

Answer:

176 g

Explanation:

44g_____2moles of O2

44×4=176 g_______8 moles of O2
