Introduction- Mass percent : It is mass by percent of compound from total mass. It can be formulated as:
(b)
Answer to Problem 67A
Explanation of Solution
Aliphatic compound are open chain structures which have straight chain whether branched or non-branched structures. They do not have any type of rings.
From the given list, ethene and propene are aliphatic compounds.
Mass percent of aliphatic compounds can be determined as:
Total mass of compound =
Total mass of aliphatic compounds =
Therefore, the mass percent of aliphatic compound is
Therefore, the mass percent of aliphatic compound is
