Question

A chemistry student needs of -methyl--pentanone for an experiment. He has available of a w/w solution of -methyl--pentanone in diethyl ether. Calculate the mass of solution the student should use

Answer 1

The question is incomplete, here is the complete question:

A chemistry student needs of 60.0 g of 4-methyl-2-pentanone for an experiment. He has available 350. g of a 14.0 % w/w solution of 4-methyl-2-pentanone in diethyl ether. Calculate the mass of solution the student should use. If there's not enough solution, press "No solution" button

Answer: There is not enough solution.

Step-by-step explanation:

We are given:

Mass of 4-methyl-2-pentanone needed = 60.0 gram

14 % w/w 4-methyl-2-pentanone solution

This means that 14 grams of 4-methyl-2-pentanone is present in 100 grams of solution

Applying unitary method:

If 14 grams of 4-methyl-2-pentanone is present in 100 grams of solution

So, 60 grams of 4-methyl-2-pentanone will be present in =
`(100)/(14)* 60=428.6g`

As, the given amount of solution is less than the calculated amount.

Hence, there is not enough solution.
