Show Limiting reactant calculations based on 3.5 mL acetic acid (using its density), and 2.5 mL isopentyl alcohol (using its density) in order to calculate theoretical grams.
Reaction includes 1 mole each of Acetic acid and isopentyl alcohol
CH3COOH+C5H12O----------------->C7H14O2+H2O
density of Acetic acid=1.05 g/mL
density of isopentyl alcohol=0.81 g/mL
Molecular mass of Acetic acid=60 g
Molecular mass of isopentyl alcohol=88g
given mass =density *volume
Given mass of Acetic acid available=1.05 g/mL*3.5mL=3.675g
Given mass of isopropyl alcohol available=0.81 g/mL*2.5=2.025g
60 g of Acetic acid requires 88g of isopentyl alcohol to react completely.
1g of Acetic acid requires 88/60g of isopentyl alcohol to react completely.
3.675g of Acetic acid requires (88/60)*3.675=5.39g of isopentyl alcohol to react completely.
Here 2.025 g of isopropyl alcohol is available only wwhich is less than required i.e 5.39g to react completely.Hence isopropyl alcohol is limiting reactant.
