Liquid nitrogen (LN2) is nitrogen in a liquid state at low temperature. Liquid nitrogen has a boiling point of about −196 °C (−321 °F; 77 K). It is produced industrially by fractional distillation of liquid air.
Also known as: Nitrogen, liquid. The units of amount of substance (e.g. mole) per milliliter, liter and deciliter are SI units of measurements of molar concentrations. millimole per deciliter [mm/dl], micromole per deciliter [µm/dl], nanomole per deciliter [nm/dl] and picomole per deciliter [pm/dl].
The Maximum Acceptable Concentration (MAC) of Pb in drinking water is 10 ppb. If a sample has concentration of 55 nM, does it exceed the MAC? Note 1: In seawater, 1 mg/L ≠ 1 ppm since the density of seawater is 1.03 g/mL. Hence, 1.00 mg/Lsewater = 1.00 mg/L x 1 mL/1.03 g x 1 L/1000 mL x 1000 mg/g = 0.971 mg/kg or 0.971 ppm
This review covers the solubility of nitrogen and air in liquids as a function of tempera ture and pressure~ Solubility data for individual systems were critically evaluated. Recom
The TKN value (Total Kjeldahl Nitrogen) represents a total nitrogen concentration, which is the sum of organic nitrogen compounds and ammonium nitrogen (TKN = org-N + NH 4-N [mg/L]). Nitrogen mainly occurs in wastewater in this form.
It tells you how concentrated a solute is in terms of g solute per 100 g water. This is simply the ratio times 100, and has units g solute/100 g solvent. Note: a rule-of-thumb, is a soluble substance has a solubility greater than 0.1g/100 g solvent, and an insoluble substance is less, but of course, that is all relevant.
