Question

The original synthesis for ibuprofen (C13H18O2), developed in the 1960s, had a percent atom economy of 40.0%%. In the 1990s, BHC Co. developed a “greener” three-step synthesis for ibuprofen with a percent atom economy of 77.5%%. In the three-step synthesis, 4 moles of H, 2 moles of C, and 2 moles of O are wasted for every mole of ibuprofen produced.

A) Calculate the total mass (in g) wasted for every one mole of ibuprofen produced

I got 60.06 g which is correct. I need help on the next two parts!

B) Yearly production of ibuprofen is approximately 27 million pounds. Calculate the number of moles of ibuprofen produced each year. (1 kg = 2.20 lbs).

C) Calculate the total mass (in kg) wasted in the annual production ibuprofen by BHC Co.’s three-step synthesis.
