1 mole of any substance contains 6.022 x 10^(23) atoms/molecules.
We have 1.5 x 10^(23) atoms
Hence
moles = 1.5 x 10^(23) / 6.022 x 10^(23) = 0.24908... moles(Mg)
Also remember the eq'n
moles = mass(g) / Ar
Algebraically rearrange
mass(g) = moles X Ar
mass = 0.24908... X 24.3 (Ar of Mg ; from Periodic Table)
Mass = 6.0528... g ~ 6 g

What is the mass of 19 atoms of copper in grams?
To calculate the mass of 19 atoms of copper in grams, you need to determine the molar mass of copper. The molar mass of copper is approximately 63.55 grams per mole. Then, you can use Avogadro's number (6.022 x 10^23 atoms per mole) to convert atoms to grams. So, the mass of 19 atoms of copper would be 19*(63.55/6.022e23) grams.
