The incorrect statement for 14g of CO is:
Correct answer: A. It occupies 2.24 litre at STP
- A. It occupies 2.24 litre at STP
- B. It corresponds to the same number of moles for 14g of CO and 14 g of N2
- C. It corresponds to 0.5 mol of CO
- D. It corresponds to 3.01 x 10^23 molecules of CO
Explanation
The question is asking for the statement which is incorrect for 14 g of CO. Upon solving each of the options we get the following results:A)22.4 dm3 at stp = 1 mole , 1 litre = 1dm3n(number of moles) of CO = mass in g/mr = 14/28 = 0.5 mol1 mol : 22.4 dm3 0.5 mol : x = 0.5 x 22.4 = 11.2 dm3/11.2 litre ;hence, this statement about 14g of CO is incorrect. B) n(number of moles) of CO = mass in g/mr = 14/28 = 0.5 mol n(number of moles) of N2 = mass in g /mr = 14/28 = 0.5 mol ;hence, this statement is correct.C) n(number of moles) of CO = mass in g/mr = 14/28 = 0.5 mol ; hence, this statement is correct. D) n(number of moles) of CO = mass in g/mr = 14/28 = 0.5 mol 1 mol : 6.02 x 1023 0.5mol : x = 0.5 x 6.02 x1023 = 3.01 x1023 ; hence, this option is also correct. Therefore, option A is the right answer as it is the only option stating incorrect information about 14g of CO.

About Fundamental Concepts of Chemistry
Mole calculations connect mass, number of particles and Avogadro's number, while balanced equations provide the mole ratios used in stoichiometry. Questions cover limiting and excess reactants, theoretical yield and percentage yield, including identifying which reactant is consumed first and comparing the actual product with the maximum possible product.
