How is the volume of a solution used in calculating concentration?​

Social Studies

Lunna [17]3 years ago

Answer:

Explanation:

Concentration is defined as mols of a chemical / volume. So volume tells you what the chemical is in.

There are other ways of defining concentration, but most of them have to do with units of volume in the denominator.

eg Concentration = grams / Liter

% solvent = grams or moles / amount of solvent (solvent is a volume)

I take a medication that is 5% active ingredient. That means that the solute is 5% of the solution and water (in this case) is 95% of the solution.

So in 100 mL of solution, 5 grams of the active ingredient is put in 95 grams of water.

Just as a note (and I don't care about it, but someone might), this looks like it should be in chemistry.

Supporting could also be counterproductive because it may send the message that the supported is unable to support themselves or get out of the situation that caused the crisis in first place, but despite this Supporting is the appropriate response to someone going through some frightening experience or crisis.
