The answer is 600. A sample of C3H8O which contains two hundred molecules, it also holds six hundred carbon atoms. A carbon atom holds six electrons, four of its electrons are found in its valence shell or also known as its outer shell.
Answer: The number of carbon atoms in 200 molecules of given sample is 600 atoms.
Explanation:
We are given a chemical compound having chemical formula [tex]C_3H_8O[/tex]
In 1 molecule of [tex]C_3H_8O[/tex], 3 atoms of carbon, 8 atoms of hydrogen and 1 atom of oxygen are present.
We need to calculate the number of carbon atoms in 200 molecules of the sample.
So, in 200 molecules of [tex]C_3H_8O[/tex], the number of carbon atoms are = [tex](3\times 200)=600[/tex] atoms.
Hence, the number of carbon atoms in 200 molecules of given sample is 600 atoms.
