Answer:
According to Avogadro's law Volume of x molecules of N2 = Volume of X molecules of O2 = V litres (Under similar T and P) (ii) Volume of X molecules of CO = Volume of X molecules of O2 = V litres ∴ Volume of 3 X molecules of CO = 3 V litres (Under similar T and P) (iv) Avogaro's Law has been used in answering the above problems
