Christopher is given identical volumes of two different solutions. he hypothesizes that solution a has a higher water concentration than solution
b. which experimental design would best allow him to test his hypothesis?

Place solution A in a membrane that is permeable to water. Then, place the membrane full of solution A into a beaker full of solution B. Make note of the direction in which water flows.

Explanation:

I took the test

materials water oxygen those are the things i can think of in this moment.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
