Question

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

Answer 1

To answer this question, the first step is to convert the given number of molecules to moles using Avogadro's number:

`5.32*10^(22)molecules\cdot(1molCO_2)/(6.022*10^(23)molecules)=0.088molCO_2`

Now, use the molecular weight of CO2 to find the mass of this amount of moles:

`0.088molCO_2\cdot(44g)/(molCO_2)=3.872g`

The mass of 5.32x10^22 molecules of CO2 is 3.872g.
