Vedclass · Answer

(C) One mole of any substance contains $6.022 	imes 10^{23}$ particles (Avogadro's number). Therefore,equal moles of different substances contain the same number of constituent particles. The Assertion is correct.The number of particles in a given weight depends on the molar mass of the substance $(n = \frac{mass}{molar \ mass})$. Since different substances have different molar masses,equal weights of different substances will contain different numbers of moles and thus different numbers of constituent particles. The Reason is incorrect.

Assertion : Equal moles of different substances contain same number of constituent particles.
Reason : Equal weights of different substances contain the same number of constituent particles.
