Mole Concepts:

Mole and Moles Analysis rule:

Ratio of Moles of reactant or product with its coefficient is always constant for a balance chemical equation:

ILLUSTRATIVE EXAMPLE (1):

ILLUSTRATIVE EXAMPLE (2):

ILLUSTRATIVE EXAMPLE (3):

ILLUSTRATIVE EXAMPLE (4):  367.5 gm KClO₃ (122.5) when heated then calculate.

(1) How many gram of O₂ is produced?

(2)How Many litre of O₂ is produced at STP?

SOLUTION:

ILLUSTRATIVE EXAMPLE (5): how many moles O₂ are required to needed produced 5 moles of Fe₂O₃.

SOLUTION:

ILLUSTRATIVE EXAMPLE (6): how many grams of Fe₂O₃ formed by heating of 18 gm FeO with O₂.

SOLUTION:
