Answer:
Approximately .
Explanation:
Make use of the molar mass data () to calculate the number of moles of molecules in that
of
:
.
Make sure that the equation for this reaction is balanced.
Coefficient of in this equation:
.
Coefficient of in this equation:
.
In other words, for every two moles of that this reaction consumes, two moles of
would be produced.
Equivalently, for every mole of that this reaction consumes, one mole of
would be produced.
Hence the ratio: .
Apply this ratio to find the number of moles of that this reaction would have produced:
.
There can be a lot of meanings for isomers. In this case, we are showing the structural isomers of C₇H₁₆. Based on the chemical formula, CₓH₂ₓ₊₂ it is an alkane. They only differ in the positions of methane branches in the parent carbon chain. Basing on the attached picture, the parent carbon chain is pentane for both isomers. But the methyl branches are on the 2nd & 4th, and 2nd & 3rd carbon for 2,4 - dimethylpentane and 2,3 - dimethylpentane, respectively.
