Question: A student reacts 1ml of acetic acid with 5ml (3.91 grams) of 1-Pentanol. Calculate the percent yield.
I think the limiting reagent is acetic acid..
Acetic Acid: 1.0ml ( 1.05g / 1ml ) ( 1 mol / 60.1g ) = 0.0175 mol
1-Pentanol: 5.0ml ( 0.8g / 1ml ) ( 1 mol / 88.15g ) = 0.0443 mol
Sulfuric acid: 1 ml ( 1.84g / 1ml ) ( 1 mol / 98.072g ) = 0.0188 mol
And for a product I got 3.58g of pentyl acetate which has a weight of 130.187g/mol. The problem I have is I need help with calculating the mole ratio. If it is 1:1 then the theoretical yield is only 2.30g which is too low.
