Answer 1.
The amount of solute in a solution gives a measurement of the concentration of the solution. Concentration is defined as moles per liter of the solution. Moles means number of grams of solute divided by the molecular weight.
So, answer is concentration.
Answer 2.
More solute means less solvent. If there are two solutions; in solution 1 concentration of solute is higher than in solution 2, then solution 1 will be called as hypertonic.
So, answer is hypertonic.
Answer 3.
If there are two solutions; in solution 1 concentration of solute is lower than in solution 2, then solution 1 will be called as hypotonic.
So, answer is hypotonic.
Answer 4.
Two solutions which have same solute concentration are called as isotonic. In such solutions, diffusion of solvent will not occur.
