Challenge Calculate the number of oxygen atoms in 5.00 mol of
gen molecules. Oxygen is a diatomic molecule, 02.

6 x 10^24  O2 atoms

Explanation:

Moles of O2  = 5.00 mol

Number of atoms = number of moles x   (6.02 x 10^23 O2 atoms / 1 mol) x (2 O atoms / 1 O2 Molecule )

                         =  5 mole 02 (6.02 x 10^23 O2 x 2) / (1 mole O2 )

                         = 6 x 10^24  O2 atoms

6.02 * 10^24 atoms

Explanation:

Step 1: Data given

Number of moles oxygen = 5.00 moles

Number of Avogadro = 6.022 * 10^23 /mol

Step 2: Calculate atoms O2

Number of atoms = moles * number of Avogadro

Number of atoms = 5.00 * 6.022 * 10^23 / mol

Number of atoms = 3.01 * 10^24 atoms

One O2- molecule contains 2 O-atoms

Number of atoms = 2* 3.01 * 10^24 atoms

Number of atoms = 6.02 * 10^24 atoms

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?
