molecular mass of HCI is 36.5u
now no. of moles present in it is 3.46/36.5 = 0.0947
multiply this no with Avogadro no. and there you have your answer.

mass of HCl = 1 * 1 + 35.5 * 1 = 1 + 35.5 = 36.5 grams
36.5 g = 6.022 * 10²³ molecules
now ,
number of molecules = given mass / molar mass * Avogadro number
⇒ N = 3.46 / 35.6 * 6.022 * 10²³
⇒ N = 0.94 * 6.022 * 10²³
⇒ N =5.66068 * 10²³
therefore number of molecules in 3.46 grams of HCl = 5.66068 * 10²³
