Question

Show, using dimensional analysis how you would calculate the % yield of 9-fluorenol (2) give the molecular weight of (2), the mole ratio of (2) to 9-fluorenone (1), the molecular weight of (1), the concentration of (1) in grams per mL, the volume of solution in mL and the weight of (2) obtained experimentally. Show the % yield in one single expression, using all the correct numbers except for the weight of (2) since you don't have this yet.

Molecular weight of (1): 180.2g/mol

Molecular weight of (2): 182.2 g/mol

Volume of solution of (1): 5mL

Concentration of (1) in g/ml: 20.00g/1000mL

Explanation / Answer

concentration in molarity of (1) = 20 g/1L x 180.2 g/mol = 0.11 M

moles of (1) taken = 0.11 M x 5 ml = 0.55 mmol

Theoretical yield of (2) would be = 0.55 x 10^-3 mol x 182.2 g/mol = 0.10 g
