Thank you for getting in touch with us for the answer of your question.
In order to find the number of molecules, firstly we need to find the number of moles as the formula to find the number of molecules is:
Number of moles x Avogadro's number
To find the number of moles:
Number of moles = Mass (g) / Molar Mass
Number of moles = 3.46 / 36.5 = 0.095
Number of Molecules = 0.095 x 6.022 x 10^23
