Question #d0338
1 Answer
See answer in explanation below
Explanation:
To figure out how many atoms there are, we want to convert to moles. We can easily convert to moles using the molar mass and the mass of the sample. However we don't know what the mass is, we just know the volume. Luckily, they gave us the density which we can use to convert from volume to mass as follows
The milliliter units cancel and leave us with an answer whose units are grams. We can use the calculated mass and the molar mass of carbon tetrafluoride which can be looked up to be
and use that to solve for moles of carbon tetrachloride as follows
Using Avagadro's Number which is
Where "a" represents atoms we can solve for the number of atoms to be
And that is your final answer
