Question: Part A: Fish Need At Least 4 Ppm Dissolved O2 For Survival. What Is This Concentration In Mol/L ? Express Your Answer Using Three Significant Figures. Part B. What Partial Pressure Of O2 Above The Water Is Needed To Obtain This Concentration At 10 4.5 mg/m³ x 24.45 L/mole = 3 ppm 34.08 g/mole Example 4 If the hydrogen sulfide concentration was measured to be 10 parts per million, what The mole fraction of solute i is written as X i. Parts Per Million(PPM) and Parts per Billion (PPB): "Parts per" is a convenient notation used for low and very low concentrations.

2000/39/. EG. SE. av R Almgren · Citerat av 5 — (Halt i mg/m3 luft = halt i ppm · molvikt i g / 24,1) 24,1 = molvolymen uttryckt i liter 4 100 kPa. Ångtryck 20 °C: 6 034 kPa.

[1] parts per million is equal to mg/liter. If you know the molar mass of the substance, then you know the number of moles. Example, if you have 50 ppm, that is 50 mg/liter. If the molar mass of the stuff is, say, 100 gm/mole that is the same as 100 mg/mmole.

This ppm to molarity formula for dilute solutions is: ppm = moles/L * molar mass * 1000 Example #4: What is the ppm concentration of calcium ion in 0.010 M CaCO 3? Solution: 1) Convert mol/L to to g/1000 g of solution: 0.010 mol/L times 40.08 g/mol = 0.4008 g/L 0.4008 g/L = 0.4008 g / 1000 g of solution Note that the solution density is assumed to be 1.00 g/mL.

The mole fraction of solute i is written as X i. Parts Per Million(PPM) and Parts per Billion (PPB): "Parts per" is a convenient notation used for low and very low concentrations. Generally speaking it is very similar to weight percentage - 1% w/w means 1 gram of substance per every 100 g of sample and it is (although very rarely) named pph - parts per hundred. Concentration Calculator and Concentration Converter: The converter allows the user to convert between different ways of expressing concentration involving mass percentage, mass-volume percentage, volume-volume percentage, molarity, normality, ppm, ppb and ppt. 2016-04-18 = 4.16 * 10^-4 mol O2. The molecular weight of O2 is 32.0 g/mol, so 4.16 * 10^-4 mol O2 = .013 g O2 = 13.3 mg O2. If the water in which the O2 is dissolved is pure H2O (not sea water) then the concentration is 13.3 mg O2 / 1000 mg H2O = 13.3 ppt dissolved O2. So 10 mL dissolved oxygen/L water = 13.3 dissolved oxygen mg/L water. Mike Evans PPM to Molarity Formula: To find the molarity from PPM, first multiply the PPM value with 0.001 and divide the resultant value by atomic weight. Formula: Molarity = ( Parts Per Million (PPM) value × 0.001 ) / Atomic Weight 2.89 ppm = 2.89 g per 1,000 L = 0.00289 g per 1 L (If you work out the mass per litre it makes working out the next steps a little easier, because the final units for molarity will be mol/L) 3) Now using the molar mass to work out the molarity (moles per litre): ppm↔ml/l 1 ml/l = 1000 ppm ppm↔ul/m3 1 ppm = 1000 ul/m3 ppm↔ug/mg 1 ug/mg = 1000 ppm ppm↔g/ton 1 ppm = 1 g/ton » Milliliter/liter Conversions: ml/l↔per 1 per = 10 ml/l ml/l↔ppm 1 ml/l = 1000 ppm ml/l↔ppb 1 ml/l = 1000000 ppb ml/l↔ppt 1 ml/l = 1000000000 ppt ml/l↔ppq 1 ml/l = 1000000000000 ppq ml/l↔g/kg 1 ml/l = 1 g/kg PPM to ml/l Converter.
