About a gaseous reaction, xX + yY lL + mM. Which statement is wrong?

JEE Main Chemistry question

About a gaseous reaction, xX + yY \rightarrow lL + mM. Which statement is wrong?

(A) litre of combines with litre of to give and
(B) moles of combines with moles of to give and
(C) number of molecules of combine with number of molecules of to form and
(D) g of combines with g of to give and Correct

Answer: (D)

Solution

Stoichiometric coefficients directly give mole ratios, and (by Avogadro's law, for gases) equally valid volume and molecule-number ratios, so (a), (b), (c) are all correct. However, mass ratios
