Ammonium fluoride molar mass. Molar Mass of Frequently Calculated Chemicals. C2H52O Ether NH42C2O4 Ammonium Oxalate NH42CO3 Ammonium Carbonate NH42CrO4 Ammonium Chromate NH42HPO4 Di-Ammonium Phosphate NH42S Ammonium Sulfide NH42SO4 Ammonium Sulfate NH43PO3 Ammonium Phosphite NH43PO4 Ammonium Phosphate Ag2O SilverI Oxide Ag2S Silver Sulfide Ag2SO4 Silver. The molar mass of a substance also often called molecular mass or molecular weight although the definitions are not strictly identical but it is only sensitive in very defined areas is the weight of a defined amount of molecules of the substance a mole and is expressed in gmol.
It can be calculated by adding the invididual molar mass of every atom that are composing the molecule CH4. Ammonium bifluoride has been considered as an intermediate in the production of hydrofluoric acid from hexafluorosilicic acid. Thus hexafluorosilicic acid is hydrolyzed to give ammonium fluoride which thermally decomposes to give the bifluoride.

The molar mass of a compound or an element is the mass per mole of the substance. The value is given in gmole or gramsmole. You can determine the molecular weight by looking up the numbers under the element names in the periodic table.
For example the chlorine molar mass is 3545 gramsmol. 115 mL of a 235 M potassium fluoride solution is diluted with 128L of water. What is the new concentration in molarity.
What is the molarity of a sodium chloride solution that contains 38 moles of sodium chloride in 25 L of the solution. What is the mass of NaCl required to prepare 05 liters of a 25 molar solution of NaCl. What is the.
Rats given 18-fluoride ion as a radiotracer by continuous iv infusion of sodium fluoride for 3 hr showed at sublethal dose rates blood fluoride concentration nears steady state proportional to fluoride infusion rateBlood kidney and lung had highest concentration at doses up to 3 mg fluoridekghr but at 6 mgkghr the fluoride of the liver spleen and hollow organs increased sharply.

A good correlation r 064 was obtained between postshift serum fluoride and postshift urine fluoride. There was a linear relationship between mean serum fluoride concentration and HF concentration in the workshop. A mean fluoride concentration of 823 ugL with a lower fiducial limit 95 P 005 of 579 ugL was estimated to correspond to an atmospheric HF concentration of 3 ppm.
The obtained osmotic pressure with formula 2 is in psi pounds per square inch. This calculator converts automatically the pressure to bar with the following conversion factor. 1 psi 6894810-2 bar.
If you do not have a water analysis you can use the values given in the right column in the input table.
