6.19*10}^{6} g of Oxygen

Explanation:

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

Avogadro´s number = 6.022*10^{23}mol^{-1}

Calculate the mass using the Avogadro´s number:

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} g of Oxygen
