To answer this question, the first step is to convert the given number of molecules to moles using Avogadro's number:
[tex]5.32\times10^{22}molecules\cdot\frac{1molCO_2}{6.022\times10^{23}molecules}=0.088molCO_2[/tex]Now, use the molecular weight of CO2 to find the mass of this amount of moles:
[tex]0.088molCO_2\cdot\frac{44g}{molCO_2}=3.872g[/tex]The mass of 5.32x10^22 molecules of CO2 is 3.872g.
