Vedclass · Answer

(C) The number of particles in a substance is given by $N = n 	imes N_A$, where $n$ is the number of moles and $N_A$ is Avogadro's constant $(6.022 	imes 10^{23} \ mol^{-1})$.Since $N_A$ is constant, equal moles $(n)$ of different substances contain the same number of constituent particles. Thus, Assertion $(A)$ is true.However, the number of moles is given by $n = \frac{w}{M}$, where $w$ is the weight and $M$ is the molar mass.Since different substances have different molar masses $(M)$, equal weights $(w)$ of different substances will result in different number of moles $(n)$, and consequently, a different number of constituent particles.Therefore, Reason $(R)$ is false.

Assertion $(A)$: Equal moles of different substances contain the same number of constituent particles.
Reason $(R)$: Equal weights of different substances contain the same number of constituent particles.
The correct answer is
