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.

chemical properties are the characteristic of matter which can only be observed by changing the chemical identity of a sample like flammability reactivity and toxicity.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer
