Question 1

-refers to a relatively large quantity of substance present in a unit amount of a mixture
-in short the amount of solute is relatively high
-usually, this means there is a lot of a solute dissolved in a given solvent
-a concentrated solution contains the maximum amount of solute that can be dissolved

Answer 1

Concentrated

Question 2

-amount of solute is relatively low
-a solution means to add more solvent without the addition of more solute

Answer 2

Diluted

Question 3

-refers to the amounts of moles
-itcan be expressed in gram or kilogram

Answer 3

Question 4

-refers to the number of moles
-it can be expressed in liter or ml

Answer 4
