Question

A sample of aspirin weighing 5.945 g became contaminated with 2.134 g of sodium sulfate. The resulting

mixture was separated by extraction with hexane. The aspirin dissolved in hexane, but the sodium sulfate did
not. The aspirin that was obtained after the separation weighed 3.739 g. What was the percent recovery of
aspirin?

Answer 1

The correct answer to the following question will be "62.9 %".

Step-by-step explanation:

The given values are:

The aspirin's initial amount = 5.945 g.

and is polluted containing 2,134 g of sodium sulfate.

After extraction we provided 3,739 g of pure aspirin.

Now,

`Percentage \ of \ recovery \ aspirin =(Aspirin \ amount \ isolated \ after \ extraction)/(initial \ amount \ of \ aspirin)* 100`

On putting the values in the above formula, we get

⇒
`=(3.739)/(5.945)* 100`

⇒
`=62.9 \ percent`

Note: percent = %
