Answer:
[tex]\boxed {\boxed {\sf 600 \ atoms \ of \ carbon}}[/tex]
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.
[tex]\frac { 3 \ atoms \ C }{1 \ molecule C_3H_2O}[/tex]
Since we want to calculate the number of atoms in 200 molecules, we can multiply the ratio by 200.
[tex]200 \ molecules \ C_3H_2O*\frac { 3 \ atoms \ C }{1 \ molecule C_3H_2O}[/tex]
[tex]200*\frac { 3 \ atoms \ C }{1 }[/tex]
[tex]600 \ atoms \ C[/tex]
200 molecules of C₃H₂O contains 600 atoms of carbon.
