ppm (parts per million) = This is weight in milligrams of CaCO3 equivalent to From this we can calculate the normality of temporary.
•ppm (mass / mass) by mass Example: 1mg / 1Kg = 1 ppm (W/W) •ppm (volume / Volume) by volume Example: 1mL/ 1 m3= 1 ppm (V/V) •ppm (mass/volume) Example: 1 mg /L = 1 ppm (W/V) •Where: one liter of water has mass of approximately one kilogram Percent verses ppm solution: 1 100 1 1000000 10000 10000ppm = ==
Use the dilution formula C1V1 = C2V2 where C concentration can be in units of molarity ppm ppb etc (200 2 ppm)(10 0 mL) = (C2)(100 0 mL) C2 = 20 02 ppm Ca 2+ One can plot a calibration curve of Absorbance versus ppm Ca2+ or other metals and obtain the slope for the relationship between absorbance and ppm 3
Parts per million ppm = (mass of solute/mass of solution) x 106 Mass per volume mg/L = mass of solute/liter of solution molality m = moles of solute/mass of solvent mole fraction ? = moles of solute/total moles Concentrations expressed as ppm and N are less familiar to most students at this stage Parts per million:
Ppm may be easily converted to percent (parts per hundred) as follows: 1 ppm = 1/1000000 = 0 000001 = 0 0001 10 ppm = 10/1000000 = 0 00001 = 0 001 200 ppm = 200/1000000 = 0 0002 = 0 02 5000 ppm = 5000/1000000 = 0 005 = 0 5 20000 ppm = 20000/1000000 = 0 02 = 2 0 Conversely the conversion of percent (parts per hundred) to ppm is
3) Calculate the mass of solvent in a 6 ppm solution of a drug if the mass of the solute is 0 050 milligrams (In this case the amount of the solute is very small and treat the solution as though the mass of solvent=mass of the solution ) 4) What is the concentration in ppm of selenium if 1 3 milligrams is found in 2500 kg of soil?
Full Scale Value ( FSV) and parts per million (ppm) FSV is sometimes also referred to as FSR (Full Scale Range) Parts per million (ppm) is usually associated with the actual unit for example 1 ppm of 1 V = 1 µV Each of these can be converted to another form by using equations and formulas
