Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

Question

5. You are given 1.56 g of a mixture of KClO3 and KC1. When the mixture is heated
the oxygen gas liberated displaces 327 mL of water at a temperature of 19°C. The
total pressure of the gas in the collection flask is 735 mmHg. What is the percentage
of KClO3 in the mixture?
