Plsssss help !! what are the steps to convert from atoms, compounds, formula units, ect to moles

Chemistry
1 answer:
Nina [5.8K]3 years ago
4 0

Answer:

Explained below.

Explanation:

From avogadro's number, we know that;

1 mole = 6.022 × 10^(23) atoms, molecules, protons e.t.c.

Now,to convert from atoms, compounds, formula units, etc to moles, what we will do is just to divide the amount of the particle value given in the specific units by avogadro's number.

For example, to convert 23 × 10^(20) atoms to moles, we will have;

Number of moles = (23 × 10^(20))/(6.022 × 10^(23)) moles = 0.00382 moles

What makes a substance pure?
Norma-Jean [14]

Answer: When a substance is pure, it is composed of one type of molecule. For example, table salt is only composed of (more or less) salt molecules, while seawater has water and salt molecules. A more complicated example of a non - pure substance is soil. It has many different types of nutrients and compounds.

Coal gas is a mixture of a variety of gases: inflammable gases including, hydrogen, methane, ethylene, carbon monoxide and volatile hydrocarbons and small amounts of non flammable gases like nitrogen and carbon dioxide.

Water gas consists mainly of carbon monoxide and hydrogen.

Producer gas is similar to water gas and consists mainly of carbon monoxide and hydrogen together with nitrogen and carbon dioxide.

Natural gas occurs naturally and consists mainly of methane with small amounts of other hydrocarbon gases.

Salt dissolved in water is a solution, therefore

  1. salt is not chemically bonded to water
  2. the ratio of salt to water may vary
  3. salt and water retain their own chemical properties

<u>Explanation:</u>

Salt (sodium chloride) is formed from positive sodium ions bonded to negative chloride ions. Water can dissolve salt because the positive part of water particles attracts the negative chloride ions of salt. The water particle effects to be charged negatively near the atom of oxygen and positively near the atom of hydrogen.

Since contrasts attract, the water molecules tend to join collectively like magnets. Water is called the universal solvent since it can solve more substances than any other liquid. The salt and water retain their unique chemical properties.
