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.
