Number of molecules = 2 moles × Avogadro’s number
2 moles × 6.022 x 1023 molecules/mole is the number of molecules.
The number of Cl₂ molecules is 1.2044 x 1023.

To determine the total number of chlorine atoms, you must double the number of molecules because each Cl₂ molecule contains two Cl atoms:

Total number of Cl atoms = 1.2044 x 1024 molecules of Cl₂ × 2 Cl atoms/molecule
Total number of Cl atoms = 2.4088 x 1024 chlorine (Cl) atoms = 2 x 2 x 6.02 x 1023 atoms.

Since the quantity of reactant provided is equal to the amount needed for a balanced chemical reaction, no reagent is the limiting reagent.

A molecular ion is a molecule that has either a positive or negative charge. An ion is referred to as a molecular ion if, after concealing its charge, it appears to be a separate, autonomous molecule. NH3+ is a cationic molecular ion if its positive charge is concealed by the thumb, indicating that it is an independent molecule of ammonia.

mass/mole and Mr

2 = mass/32

64 g is the mass.

Option A is therefore accurate.

Mole= Mass/ relative atomic mass.

Mole x Relative Atomic Mass = Mass

Mass is equal to 2 x 32.(The fact that oxygen gas is written as O2 means that O2 is 32.)

64g is the mass.

A gram molecule, also known as a mole, is a molecule whose molecular mass is expressed in grams; therefore, the molar mass of O2 is 32 g.

FACT

The term “mole” is used to express the amount of a substance in relation to Avagadro’s number, which is a constant that represents the number of atoms or molecules in one mole of a substance.

Cobalt isotopes are used to treat cancer (Rote Learning).
