Chapter 26: Problem 8

a) What number of carbon atoms are found in one dozen methane, \(\mathrm{CH}_{4}\), molecules? b) What number of carbon atoms is found in one dozen carbon tetrachloride, \(\mathrm{CCl}_{4}\), molecules?

Short Answer

Expert verified
There are 12 carbon atoms in a dozen methane molecules and 12 carbon atoms in a dozen carbon tetrachloride molecules.

Step by step solution

01

Understand the Composition of Molecules

First, it's required to understand the composition of the given molecules. For a molecule of Methane (\(\mathrm{CH}_{4}\)), there's only one carbon atom and in a molecule of Carbon Tetrachloride (\(\mathrm{CCl}_{4}\), there's just one carbon atom as well.
02

Calculate the Carbon Atoms for Methane

To calculate the number of carbon atoms in a dozen Methane molecules, multiply the number of molecules (a dozen, which is 12) by the number of carbon atoms in one molecule of Methane, which is 1. This gives 12 x 1 = 12 carbon atoms.
03

Calculate the Carbon Atoms for Carbon Tetrachloride

Similarly, to calculate the number of carbon atoms in a dozen Carbon Tetrachloride molecules, multiply the number of molecules (a dozen, which is 12) by the number of carbon atoms in one molecule of Carbon Tetrachloride, which is 1. This again gives 12 x 1 = 12 carbon atoms.
