Is each of the following statements true or false? Correct any that are false.
adell [148]

<u>True,</u> A mole of one substance has the same number of atoms as a mole of any other substance.

<h3>What is a mole?</h3>

Mole, also spelled mol, in chemistry, a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.

The mole designates an extremely large number of units, 6.02214076 × 10^{23}. The General Conference on Weights and Measures defined the mole as this number for the International System of Units (SI) effective from May 20, 2019. The mole was previously defined as the number of atoms determined experimentally to be found in 12 grams of carbon-12.

The number of units in a mole also bears the name Avogadro’s number, or Avogadro’s constant, in honour of the Italian physicist Amedeo Avogadro (1776–1856). Avogadro proposed that equal volumes of gases under the same conditions contain the same number of molecules, a hypothesis that proved useful in determining atomic and molecular weights and which led to the concept of the mole.

One one molecule of sodium oxide has one sodium atome (Na) and two oxygen atoms (O).

The subscript after element shows the number of elements in a molecule.

2) Yes, it possible for two different compounds to be made from the exact same two elements.

This are isomers, same molecular formula, but different arrangements of atoms.

For example, n-butane (C₄H₁₀) and 2-methylpropane (C₄H₁₀).

3) There are large number of compounds in this world, around 40 millions.
