One goal of biomass conversion is the development of feedstocks, chemicals that can be easily converted to raw materials for chemical processes like the synthesis of polymers. One important feedstock molecule that can be derived from biomass is 2-propanol, C₃H₇OH. If 423 moles of the compound are needed for a reaction, how many pounds of C₃H₇OH should be used?

Strategy We are asked to convert from a number of moles to a mass. We know that the link between these two quantities is the molar mass of the compound, so we can start by calculating that. Once we know the molar mass, we can use it to find the required mass of 2-propanol. Finally, we can convert that result from grams to pounds.
