A 4.50 g4.50\text{ g}4.50 g sample of benzoic acid (Mr=122.0M_r = 122.0Mr=122.0) is reacted with 6.00 cm36.00\text{ cm}^36.00 cm3 of methanol (Mr=32.0M_r = 32.0Mr=32.0) to produce methyl benzoate (Mr=136.0M_r = 136.0Mr=136.0) according to a 1:1 stoichiometric ratio.
In this preparation, the percentage yield of methyl benzoate is 68.0%68.0\%68.0%. The density of methanol is 0.79 g cm−30.79\text{ g cm}^{-3}0.79 g cm−3.
Show by calculation which reagent is in excess and calculate the mass, in g\text{g}g, of methyl benzoate produced.
