Summarize what concentration means using the terms solute, solvent and number of particles. The amount of solute and number of particles that are dissolved in a solution.

Answer 1

Concentration is a measure of how many particles of a solute are dissolved in a given quantity(amount) of solvent.

Example: 5 grams of salt (NaCl) are dissolved in 100 ml of water. The NaCl concentration is 5 grams/100 ml.

It can also be expressed as 0.5 g/liter, or in other units such as moles/liter (Molar).
