There is no comparable easy way to experimentally measure the change in entropy for a reaction
Consider: a scientific inference is an idea or conclusion that is drawn from evidence and reasoning. In other words, it is an educated guess based on information you already know.
1 mol = 6.022 x 10²³ atoms
In order to find how many atoms, dimly multiply the amount of moles you have by 6.022 x 10²³ or Avogadro's number.
So you have 1.75 mol CHC1₃ x (6.022x10²³) = 1.05385 x 10²⁴ atoms of CHCl₃
But now you have to round because of the rules of significant figures so you get 1.05 x 10²⁴ atoms of CHCl₃
Answer:
major enantiomer = 90.5 %
minor enantiomer = 9.5 %
Explanation:
Assuming that the major isomer is in excess;
From, ee/2 + 50
ee = enantiomeric excess = 81%
% major
=81/2 + 50 = 90.5 %
% minor
= 100% - 90.5 %
% minor
= 9.5 %

Natural selection is what nature it self makes to enhance or mutate the species for survival of the finest but selective breeding is where humans mutate animals or plants to make them better, whether of use or taste, for our use.
