Answer: [tex]10.17\times 10^{-23}g[/tex]
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.
To calculate the number of moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given atoms}}{\text{Avogadro's number}}=\frac{1}{6.023\times 10^{23}}=0.16\times 10^{-23}atoms[/tex]
1 mole of zinc weighs = 65.38 g
[tex]0.16\times 10^{-23}[/tex] moles of Zinc weigh = [tex]\frac{63.58}{1}\times 0.16\times 10^{-23}=10.17\times 10^{-23}g[/tex]
Thus mass of one atom of Zinc weigh [tex]10.17\times 10^{-23}g[/tex]
