How many total atoms of oxygen are present in the molecules represented here?
Answer:
The answer is 36 atoms
Explanation: I took the test and i got 100%
There are 36 oxygen atoms in the representation "6 C₆H₁₂O₆".
We have the expression "6 C₆H₁₂O₆", which represents 6 molecules of C₆H₁₂O₆.
The subscripts are the atomicities of the element, that is, the number of atoms of each element in 1 molecule.
There are 6 atoms of oxygen per molecule of C₆H₁₂O₆. Considering that there are 6 molecules, the total number of atoms of oxygen are:
[tex]6 Molecules \times \frac{6\ O\ atoms}{1Molecule} = 36\ O\ atoms[/tex]
There are 36 oxygen atoms in the representation "6 C₆H₁₂O₆".

how do the melting points of enantiomers compare to each other? how do the melting points of diastereomers compare to each other?
Melting points of enantiomers will not compare to each other as they have same M.P. and Diastereoisomers are compared on the basis of melting point.
What are steroisomers?Stereoisomers are those isomers which are having the same molecular formula but different spatial arrangemet of atoms within the molecule.
Enantiomers: Enantiomers are pair of two stereoisomers which are having mirror image of each other, but are not superiposable. They have the same melting point so we can not compare enantiomers on the basis of their melting point.Diastereoisomers: Diastereoisomers are pair of those stereoisomers which are not having mirror image of each other, but are superimposable.They have different physical and chemical properties, so it can be compared on the basis of melting point.Hence, only diastereoisomers are compared on the basis of melting point.
