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

Answer:

The mass of solution will be "395.78 g".

Explanation:

Given:

Mass of acetic acid,

= 30 g

Percentage,

= 7.58% w/w

Now,

⇒ % $=\frac{Mass \ of \ acetic \ acid}{Mass \ of \ solution}\times 100$

By putting the values, we get

⇒ $7.58=\frac{30}{Mass \ of \ solution}\times 100$

⇒ $Mass \ of \ solution=\frac{30\times 100}{7.58}$

⇒                               $=\frac{3000}{7.58}$

⇒                               $=395.78 \ g$
