Question

How to find moles if molecules of compound is given?

Answer 1

Avogadro's number is a very important relationship to remember:

1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro's number.

To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).
