Solutions, Molarity and Dilution - Definitions and examples of how to calculate wt%, molarity and how to prepare dilutions.

Soft or Hard Water - Carbonates dissolved in water.

Particle Size - The size of dust particles, pollen, bacteria, virus and many more.

Oxygen and Corrosion of Steel Pipes - Oxygen concentration and temperature and the influence on corrosion of steel pipes.

Diffusion constants for several gases in water.

Gases Solved in Water - Diffusion Coefficients - Diffusion flux tells how fast a substanse solved in another substance flows due to concentration gradients.

Clean Rooms - Federal Standard 209 - Clean rooms virtually free of contaminants like dust or bacteria.Apothecaries' Weight System - Apothecaries' fluid and weight system - ounce, drachms, grains, scruples.Ammonia - NH 3 - Concentration in Air and Health Effects - Ammonia and health symptoms - smell and threat to life.Air Contaminants - Limits - Permissible limits to exposure of various air contaminants.Basics - The SI-system, unit converters, physical constants, drawing scales and more.Molality is the number moles of solute divided by kilograms of solvent. Molarity is the number of moles of solute (substance of interest - pollution, etc.) dissolved in one liter (volume) of the solution. Percent by volume = 100 v c /(v c + v s) (3) Volume percent can be expressed as volume per unit volume:

The volume of carbon dioxide in one 1 m 3 of air can be calculated by modifying (1) to The concentration of carbon dioxide in air is aprox. = 8.345 pounds per million gallons of water Example - Volume Concentration of Carbon Dioxide in Air Weight of substance added to one unit volume of water to give one part per million (ppm) The concentration of a component can be measured as mass per unit volume - like mg/liter, mg/cm 3 etc. Weight percent = 100 m c / m s (2) ppm vs.

ppq - parts per quadrillion (1 / 1,000,000,000,000,000 or 10 -15)Īn alternatively mass related unit to measure larger concentration levels is weight percent which can be expressed as.

percent and mg/L chartĪlternatively - mass related units to measure very small concentration levels: In the metric system ppm for mass can be expressed in terms of milligram versus kg whereĭownload and print ppm vs. S = molar mass, volume or mass of solution (mole, m 3, ft 3, kg, lb m) ppm is defined asĬ = molar mass, volume or mass of component (mole, m 3, ft 3, kg, lb m) Parts per million is the molar mass, volume or mass ratio between the pollutant component and the solution. Parts per million - ppm - is commonly used as a dimensionless measure of small levels (concentrations) of pollutants in air, water, body fluids, etc.
