Vedclass · Answer

(A) To find the number of molecules in a given amount of substance,we use Avogadro's number $(N_A = 6.022 	imes 10^{23} 	ext{ molecules/mole})$.The formula is: $	ext{Number of molecules} = 	ext{Number of moles} 	imes N_A$.Given,number of moles = $0.5$.Therefore,$	ext{Number of molecules} = 0.5 	imes 6.022 	imes 10^{23}$.$= 3.011 	imes 10^{23} 	ext{ molecules}$.
