The molar mass of propan-2-ol is 60.1g/mol.
You've established that each sterilizing pad contains 0.6g of propan-2-ol, so we can discover how many moles of propan-2-ol is in a typical sterilizing pad by multiplying the average amount of propan-2-ol in one pad by the molar mass of propan-2-ol, 60.1g/mol.
0.6g x 60.1g/mol = 36.06 moles.
