Dichlorobenzene
There are 13 atoms in C6H4Cl2: 6 carbon atoms, 4 hydrogen atoms, and 2 chlorine atoms.
Nonane has a total of 75 isomers, which includes straight chain isomers, branched chain isomers, and cyclic isomers.
To calculate the number of moles of carbon atoms in dichlorobenzene, we need to determine the molar mass of C6H4Cl2. The molar mass is 147.009 g/mol. Using the given mass of 3.982 g, we can calculate the number of moles using the formula moles = mass/molar mass. So, moles of C6H4Cl2 = 3.982 g / 147.009 g/mol = 0.0271 moles of C6H4Cl2. Since there are 6 carbon atoms in each molecule of C6H4Cl2, the number of moles of carbon atoms would be 6 times the moles of the compound, which is 0.0271 moles x 6 = 0.1626 moles of carbon atoms.
