Question

The average mass of one gold atom in a sample of naturally occurring gold is $3.27 \times 10^{- 22}$ g. Calculate the molar mass of gold. (Nearest integer)

Open in App

Solution

The molar mass of gold is obtained by multiplying the average mass of an atom with Avogadro's number.
The molar mass of gold is $3.270710 \times 10^{- 22} \times 6.023 \times 10^{23} = 196.2$ g/mole.
