How do you convert moles of aspirin to grams of aspirin?

Chemical Engineers sometimes measure substance amount in units of gram-moles, kilogram-moles, pound-moles, or ounce-moles; these measure the quantity of a substance whose molecular weight is not...

You must first find the molar mass of the element or compound. Use the periodic table (see the Related Link). If the chemical is an element, just read off the atomic mass from the periodic table. If...

first you must have a mass in mind. eg 345 grams of Carbon divided the mass by the molar weight of the particular substance. In the case of Carbon 12 grams/mole 345 grams/12 grams/mole = 28.75 moles

Multiply no. of moles with the molecular mass of water i.e 18g to get the mass of water in grams

Divide grams by the molar mass of the substance.
