I got 1.97! How did you guys get 4.8?

You are asked to find the mass of butan-2-ol required to produce 3 g of butanone i think. ( i dont really remember the question)
(3/72.1) * 74.1 = 3.08g

(x/3.08) * 100 = 64
x= 1.97g <-- If you take 3.08 as 100 % yield

(3.08/x) * 100 = 64
x=4.82g <-- If you take 3.08 as 64 % yield

that's how people got different answers
