Explanation:
We are given this compound with the formula: C₃H₂O
According the subscripts, 1 molecule contains 3 carbon atoms, 2 hydrogen atoms, and 1 oxygen atom.
We can make a ratio. There are 3 carbon atoms for every 1 molecule of C₃H₂O.
![\frac { 3 \ atoms \ C }{1 \ molecule C_3H_2O}](https://tex.z-dn.net/?f=%5Cfrac%20%7B%203%20%5C%20atoms%20%5C%20C%20%7D%7B1%20%5C%20molecule%20C_3H_2O%7D)
Since we want to calculate the number of atoms in 200 molecules, we can multiply the ratio by 200.
![200 \ molecules \ C_3H_2O*\frac { 3 \ atoms \ C }{1 \ molecule C_3H_2O}](https://tex.z-dn.net/?f=200%20%5C%20molecules%20%5C%20C_3H_2O%2A%5Cfrac%20%7B%203%20%5C%20atoms%20%5C%20C%20%7D%7B1%20%5C%20molecule%20C_3H_2O%7D)
![200*\frac { 3 \ atoms \ C }{1 }](https://tex.z-dn.net/?f=200%2A%5Cfrac%20%7B%203%20%5C%20atoms%20%5C%20C%20%7D%7B1%20%7D)
![600 \ atoms \ C](https://tex.z-dn.net/?f=600%20%5C%20atoms%20%5C%20C)
200 molecules of C₃H₂O contains 600 atoms of carbon.
