To find the mass of a single gold atom, we can use the information provided.
The periodic table lists the mass of gold as 0.197 kg per 6.02 * 10^23 atoms.
This means that 0.197 kg of gold contains 6.02 * 10^23 atoms.
To find the mass of a single gold atom, we divide the mass of gold by the number of atoms:
Mass of a single gold atom = 0.197 kg / (6.02 * 10^23 atoms)
Calculating this:
Mass of a single gold atom ≈ 3.27 * 10^-25 kg
Therefore, the mass of a single gold atom is approximately 3.27 * 10^-25 kg.
