14.4 Solution Equilibrium and Factors Affecting -- Part 2
The polychlorinated biphenyls population is going to recover.
The chemicals on this list have been banned.
The bald eagle population is estimated to have 10,000 pairs.
The bald eagle has been removed from the threatened species list because of the strong recovery.
The EPA monitors the presence of these contaminants in water supplies.
The maximum contaminant levels are set by the EPA.
Some compounds in water supplies are listed in Table 14.7%.
The EPA uses units to express the concentration of the contaminants.
The mass of the pollutant is converted into liters of water by this unit.
The water is safe to drink if the contaminant concentrations are below the EPA's guidelines.
Potentially harmful chemicals can make their way into water sources.
The organisms consume the Dioxin.
These chemicals move up the food chain.
Divide the amount in moles by the volume of the solution in liters.
The mass solution of the solute and solvent should be 100%.
To calculate mole fraction, first deter 1 mol H2O mine the amount of water in moles mol H2O.
The mole fraction can be calculated using the mol % and xsolute * 100% mole fraction.
The density of the solution is 1.03 g/mL and the C6H12O6 centration is 6.51%.
To get molarity, divide the numerator by the denominator.
