One step in making para-aminobenzoic acid, paba, an ingredient in some suntan lotions,
involves replacing one of the hydrogen atoms in a toluene molecule with an - no2 group,
directly opposite the -ch3 group. calculate the percent yield if 550 g of toluene added to an
excess of nitric acid provides 305 g of the nitrotoluene product.
