Tia has a sample of pure gold (au). she weighed the sample and the result was 35.9 grams. tia wants to determine the number of atoms in the sample. calculate the number of atoms in 35.9 g of pure gold.

of gold.

Explanation: To calculate the moles, we use the equation:

For gold

Mass of gold given = 35.9 g

Molar mass of gold = 197 g/mol

Putting values in above equation, we get:

According to Avogadro's law, 1 mole of every substance contains avogadro's number of particles.

Thus 0.18 moles of gold will contain= atoms of gold.
