Question #b7094

Answer 1

You calculate how many atoms are in 1 mole of `"H"_2"O"` by using Avogadro's number.

Explanation:

You'd go about calculating this by using Avogadro's number, which links the number of atoms or molecules of a substance with the number of moles of that substance you have.

According to this relationship, every mole has `6.022 * 10^(23)` atoms (or molecules, depending on the substance).

Since water is a molecule, 1 mole of water will always have `6.022 * 10^(23)` molecules of water.

LIkewise, 1 mole of `"O"_2`, for example, will have `6.022 * 10^(23)` molecules of diatomic oxygen, 1 mole of sulfuric acid will have `6.022 * 10^(23)` `H_2SO_4` molecules, 1 mole of copper will have `6.022 * 10^(23)` atoms of copper, and so on.
