Ibuprofen has the formula C13H18O2. Calculate, (i) the mass, in g, of 0.525 moles of ibuprofen....
Ibuprofen is an anti-inflammatory with the formula C13H18O2. How many grams of ibuprofen are in 0.495 mol? How many moles of carbon are in 10.0 g of ibuprofen? How many moles of ibuprofen contain 1.15×1023 atoms of carbon?
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...
