Activity 2: Complete the paragraph by fill in the blank with the correct word. Choose your answer from the word bank below.
The concentration of (1) _______________________ describes the relative amounts of solute and solvent in a given volume of solution. Concentration can be described qualitatively as either concentrated or diluted. When there is a large amount of dissolved solute for a certain volume of solvent, the solution is (2) _______________________. A (3) _______________________ solution has a small amount of dissolved solute in comparison to the amount of solvent.
Concentration of solution can be express (4) _______________________ using percent composition. Percent composition refers to the percent of the (5) _______________________in the solution. In expressing the percent concentration, the units (6) _______________________or volume are used. Percent composition can be express using percent by volume and percent by mass. Percent by (7) _______________________ is the amount of solute in a given volume of solution expressed as grams or mL of solute per 100 (8) ________________of solution. Percent by mass refers to the amount of solute in a given mass of (9) _______________________expressed as grams solute per 100 (10) _______________________ of solution.
