What is the percent by volume of a solution formed by adding 15 L of acetone to 28 L of water?

34.88 %

Explanation:

To solve this question, we are going to assume that the acetone has 100% solution.

We know that 15 L of acetone was added to 28 L of water

We need to determine the percent by volume of a solution as

15 L of acetone/ (15L of acetone +28L of water)

= 15L/43L

=0.3488

= (0.3488×100%)

= 34.88 %

Hence, the percent by volume of a solution formed is 34.88

its been noted for the past decade or so that there is some (approximately 5% to 7%) shrinkage in the brains of people who have schizophrenia, most notably in the gray matter, which is an important part structures in the brain’s amygdala, hippocampus and parahippocampus, which are all involved in memory storage and retrieval memory storage and retrieval.
