Question

An oxide of nitrogen has a molecular weight 92.Find the total number of electrons in one gram mole of that oxide.

A
4.6 N
B
46 N
C
23N
D
2.3 N

Solution

The correct option is B 46 NThe atomic number of nitrogen $$(N)$$ and oxygen $$(O)$$ are one half $$(1/2)$$ their mass numbers.$$\therefore$$  One molecule of compound having molecular weight of $$92$$ will contain $$46$$ electrons.So, $$1gm$$ mole of molecule will contain $$46N$$ no. of electrons, where $$N$$ is the Avogadro Number.Ans. will be (B).Chemistry
