Question

Which term is the same for one mole of oxygen and one mole of water? 1. Volume 2. Mass 3. Atoms 4. Molecules

Answer 1

But the common thing between one mole of O2 and one mole of H2O is that both contain the same number of particles which is 6.02*10^23.

This number is called Avogadro's constant.

One mole of any substance contains 6.02*10^23 particles of that substance.

ALSO YOUR CORRECT ANSWER WILL BE MOLECULES

Answer 2

Answer:

The term 4. Molecules is the same for one mole of oxygen and one mole of water.

Explanation:

• One mole of an atom has 6.022×10²³ molecules.
• This number is known as Avogadro's number or Avogadro's constant.
• The Avogadro constant is the proportionality factor that relates the number of constituent particles in a sample with the amount of substance in that sample.

Explanation for incorrect options:

1. Volume

The volume depends upon the mass of the substance.

The mass of one mole of oxygen differs from the mass of one mole of water.

2. Mass

The mass of one mole of oxygen is 16grams and that of one mole of water is 18g/mol.

3. Atoms

The number of atoms in oxygen is 2 (O₂) and the number of atoms in water is 3 (H₂O).
