Interpretation
The mass percent of naphthalene in the given solution should be calculated.
Concept introduction
Percent by mass: It is the ratio of solute mass to the solution mass which finally multiplied by
Moles: One mole is equivalent to the mass of the substance consists same number of units equal to the atoms present in
From given mass of substance moles could be calculated by using the following formula,
Mass: It is the quantitative measure of a substance. The amount of matter present in substance is expressed as mass. The

- A. B. b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry.
