Question

A chemistry student needs 30.0 g of acetic acid for an experiment. He has available 1.2 kg of a 7.58% w/w solution of acetic acid in acetone.

Calculate the mass of solution the student should use. If there's not enough solution, press the "No solution" button.
Round your answer to 3 significant digits.

Answer 1

The mass of solution will be "395.78 g".

Step-by-step explanation:

Given:

Mass of acetic acid,

= 30 g

Percentage,

= 7.58% w/w

Now,

⇒ %
`=(Mass \ of \ acetic \ acid)/(Mass \ of \ solution)* 100`

By putting the values, we get

⇒
`7.58=(30)/(Mass \ of \ solution)* 100`

⇒
`Mass \ of \ solution=(30* 100)/(7.58)`

⇒
`=(3000)/(7.58)`

⇒
`=395.78 \ g`
