Collecting Reactants – Level 2 A student is attempting to collect all of their reactants for the nitration of methyl benzoate lab.10.10 mL of methyl benzoate completely reacted with nitric acid to produce methyl 3-nitrobenzoate using sulfuric acid as a catalyst.  What is the minimum volume (mL) of nitric acid required to add one stoichiometric equivalent of nitro group to the starting material methyl benzoate? Given: Methyl benzoate | C8H8O2 | M.W. = 136.15 g/mol | Density = 1.08 g/mlNitric acid | HNO3 | Aqueous Concentration = 15.9 M Methyl 3-nitrobenzoate | C8H8NO4 | M.W. = 181.15 g/mol SELECT THE CLOSEST ANSWER POSSIBLE.
