# How Many Atoms Are In A Gram Of A Compound?

To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro’s number: 6.02 x 10^23.

## How many atoms are in a compound?

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).

## How do you find the grams of an element in a compound?

To find the molar mass of a compound:

• Use the chemical formula to determine the number of each type of atom present in the compound.
• Multiply the atomic weight (from the periodic table) of each element by the number of atoms of that element present in the compound.

## How many atoms are in 1g of gold?

How many atoms of gold(proton number 79) are there in a pure gold ring with a mass of 3.94g? many atoms or molecules, atoms in this case, contained in your object. 30,573,183,730,000,000,000 = 30.573 Billion-Billion Atoms of Gold in 1 gram.
