Is there a way to determine the number of moles in a sample of a substance?

Yes, there is. You can use the formula n = (moles of solute) / (molecular weight of solute). For example, if you have a solution with a molecular weight of 100 g/mol and you want to know how many moles are present in 1 liter of that solution, you would divide the molar mass by the volume of your solution to find out how many moles per liter are present.
