Stoichiometry

Q1: What is the simplest formula of a compound containing 50% of element A (atomic weight = 10) and 50% of element B (atomic weight = 20) ?

A AB3

B A2B3

C A2B

D AB2

ANS:A - AB3

To determine the simplest formula of the compound, we need to find the ratio of atoms of each element in the compound. Given:

  • Element A (atomic weight = 10) constitutes 50% of the compound.
  • Element B (atomic weight = 20) constitutes 50% of the compound.
Since the compound is composed of equal parts of both elements, we can consider a 1:1 ratio of atoms of A and B. To achieve this, the simplest formula of the compound would be AB. Therefore, the correct option is: C) AB
