assuming that in the hydrolysis step you have 1 mole of p-nitroacetanilide and 300 mL of 6 M HCl. After the neutralization, you end up with 100 g of p-nitroaniline. a)what is the limiting reactant? B)percent yeild
p-nitroacetanilide + 6 M HCl ----> p-nitroaniline
no of moles of p-nitroacetanilide = 1 moles
no of moles of HCl = molarity of HCl x volume of HCl in liters = 6 M x 0.3L = 1.8 mole
for one mole of p-nitroacetanilide 1.8 mole of HCl taken means limiting agent is p-nitroacetanilide
so limiting agent is p-nitroacetanilide
B)percent yeild
they isolated 100 grams of p-nitroaniline
no of moles of p-nitroaniline = weight of p-nitroaniline / molar mass of p-nitroaniline = 100 g / 138.13 g /mol =
=0.724 mol
formula for the percentage of yield is
% of yield = (moles of products / moles of reactants ) x 100
= (0.724 / 1) x 100
= 72.4 %
