A sample of C3H8O that contains 200. molecules contains ________ carbon atoms.

600

Go back and read the response I made to the Ba(OH)2 problem and you'll have this one worked. If I have C3H8O, I know there are 3 C atoms per molecule of C3H80; therefore, if I have 200 molecules of C3H80, I must have 600 atoms of C, 1600 atoms of H and 200 atoms of oxygen.

To find the number of carbon atoms in a sample of C3H8O containing 200 molecules, we need to determine the atomic composition of the molecule and then calculate the number of carbon atoms.

The chemical formula C3H8O tells us that the molecule contains 3 carbon atoms (C), 8 hydrogen atoms (H), and 1 oxygen atom (O).

To calculate the number of carbon atoms, we need to multiply the number of carbon atoms per molecule by the total number of molecules.

In this case, since each molecule contains 3 carbon atoms, we can calculate the total number of carbon atoms by multiplying 3 by 200.

Number of carbon atoms = 3 x 200 = 600

Therefore, the sample of C3H8O containing 200 molecules contains 600 carbon atoms.

To calculate the number of carbon atoms in a sample of C3H8O, also known as isopropyl alcohol, you need to understand the chemical formula and structure of the molecule.

In C3H8O, the subscripts indicate the number of each type of atom present. There are 3 carbon atoms (C), 8 hydrogen atoms (H), and 1 oxygen atom (O).

To determine the number of carbon atoms in a sample of 200 molecules, you'll need to multiply the number of molecules by the number of carbon atoms in each molecule.

Thus, the calculation is:
Number of carbon atoms = Number of molecules × Number of carbon atoms per molecule

Number of carbon atoms = 200 molecules × 3 carbon atoms per molecule

Number of carbon atoms = 600 carbon atoms

Therefore, a sample of C3H8O that contains 200 molecules would contain 600 carbon atoms.
