Concept explainers
(a)
Interpretation:
The Lewis structure of DHA needs to be determined.
Concept Introduction :
Lewis structure shows the arrangement of valence electrons in an atom of molecule. The electrons involved in bonding are represented as bonds between the atoms and electrons which are not involved in bonding are represented as lone pair of electrons on the atom.
(b)
Interpretation:
The polar and non-polar covalent bonds in DHAneeds to be determined.
Concept Introduction : Polar covalent bonds are those in which there is difference in electronegativity of atoms bonded together on the other hand, non-polar covalent bonds are those in which there is no electronegativity difference. .
(c)
Interpretation:
The molecular formula and molar mass of DHA needs to be determined.
Concept Introduction : Molecular formula of a compound can be determined from its structure by calculating the total
Molar mass is calculated by taking sum of
(d)
Interpretation:
The volume of DHA in a lotion bottle as per the given information needs to be determined.
Concept Introduction :
Mass percent of a compound in sample is defined as percent ratio of mass of the component to total mass of sample.
