Q. Consider the following data :
Element Atomic weight
A 12
B 35.5

$A$ and $B$ combine to form a new substance $X$. If four moles of $B$ combine with one mole of $A$ to give one mole of $X$, then the weight of one mole of $X$ is

Some Basic Concepts of Chemistry

Solution:

$A+4 B \to X$ ( i.e., $\left.A B_{4}\right)$

Hence, $1 \,mol$ of $X=12+4 \times 35.5=154 \,g$
