How do you figure this question out in CHEM 101?What is the mass in grams are in 5.32x10^22 molecules of CO2?

Sagot :

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.
