How to calculate atoms from moles?

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). read more

The answer is 6.0221415E+23. We assume you are converting between atom and mole. You can view more details on each measurement unit: atom or mole The SI base unit for amount of substance is the mole. 1 atom is equal to 1.660538863127E-24 mole. Note that rounding errors may occur, so always check the results. read more

To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms. For example, the molar mass of NaCl can be calculated for finding the atomic mass of sodium (22.99 g/mol) and the atomic mass of chlorine (35.45 g/mol) and combining them. read more
