Answer:

[tex]6.19*10}^{6}[/tex] g of Oxygen

Explanation:

In order to answer the question the Avogadro´s number is needed:

Avogadro´s number = [tex]6.022*10^{23}[/tex][tex]mol^{-1}[/tex]

Calculate the mass using the Avogadro´s number:

[tex]2.33*10^{20}atomsO*\frac{1molO}{6.022*10^{23}atomsO}*\frac{16gO}{1molO}*\frac{1*10^{9}g}{1g}=6.19*10}^{6}[/tex] g of Oxygen
