Molar mass is the mass of each element multiplied by subscript, then added together.

So, we’ll do

C = 12g x 12 = 144 g
H = 1g x 22 = 22 g
O = 16g x 11 = 176 g

The total of all of these is the molar mass: 342 g in a mol

The amount of mols of each element in each compound is likely equal to its subscripts.

C = 12 mols
H = 22 mols
O = 11 mols

For the atoms, you’ll multiply each one of the above by Avogadro’s number

Avogadro’s Number: 6.02 x 10^23 atoms/mol

Each of the following names is wrong. Draw structures based on them, and correct the names:(b) 1,1,1-trimethylheptane
devlian [24]

The correct IUPAC name of 1,1,1-trimethylheptane is 2,2-dimethyloctane.

<h3>IUPAC NAME:</h3>

It is systematic way of nomenclature of organic compounds.

It is based on the position of functional groups, preference of the functional group, long or short chain of carbon, preference of double bond, single and triple bond, branching of carbon chain, etc.

The given compound is 1,1,1-trimethylheptane.

The given name is wrong according to IUPAC name because the numbering of carbon atom should be done in that way in which the carbon atom chain is largest.

Here, in this case the numbering is done from right side. Thus the largest carbon chain have 8 carbon atom.

If the numbering is done according to the question, number of carbon atom in straight chain is 7.

Thus, we concluded that the Correct IUPAC name of 1,1,1-trimethylheptane is 2,2-dimethyloctane.
