Interpretation:
The amount of NaF (in grams) consumed per day is to be calculated.
Concept Introduction:
Solutions are homogeneous mixtures made up of two components, the solute and the solvent.
The same solutes and solvents can form a number of combinations by varying their amounts. These combinations can be differentiated in terms of concentration of solutions. Concentration of a solution is defined as the amount of solute present in the given amount of solvent.
There are many ways of expressing concentration of solutions, such as mass percent, volume percent, molarity, parts per million.
Mass percent is defined as the mass of solute present in
Volume percent is defined as the mass of solute present in
Parts per million is defined as the mass of solute present in
It is known

- Classify each of the following solutions as saturated, unsaturated, or supersaturated based on the following observations made after adding a small piece of solid solute to the solution. a. The added solute rapidly dissolves. b. The added solute falls to the bottom of the container where it remains without any decrease in size. c. The added solute falls to the bottom of the container where it decreases in size for several hours and thereafter its size remains constant. d. The added solute causes the production of a large amount of solid white crystals.arrow_forwardFor each of the following pairs of solutions, select the solution for which solute solubility is greatest. a. Oxygen gas in water with P = 1 atm and T = 10C Oxygen gas in water with P = 1 atm and T = 20C b. Nitrogen gas in water with P = 2 atm and T = 50C Nitrogen gas in water with P = 1 atm and T = 70C c. Table salt in water with P = 1 atm and T = 40C Table salt in water with P = 1 atm and T = 70C d.
