Vedclass · Answer

(D) The molar mass of water $(H_2O)$ is $18 \ g/mol$.The number of moles $(n)$ is calculated as $n = \frac{	ext{mass}}{	ext{molar mass}} = \frac{180 \ g}{18 \ g/mol} = 10 \ moles$.The number of molecules is calculated as $n 	imes N_A = 10 	imes 6.023 	imes 10^{23} = 6.023 	imes 10^{24}$ molecules.Therefore,the correct option is $D$.
