4 and OH − do not account for a significant fraction of the total amount of ammonia except in extremely dilute solutions. [6] The concentration of such solutions is measured in units of the Baumé scale , with 26 degrees Baumé (about 30% of ammonia by weight at 15.5 °C or 59.9 °F) being the typical high-concentration commercial product.
The hazards of ammonia solutions depend on the concentration: 'dilute' ammonia solutions are usually 5–10% by weight (< 5.62 mol/L); 'concentrated' solutions are usually prepared at >25% by weight. A 25% (by weight) solution has a density of 0.907 g/cm 3 , and a solution that has a lower density will be more concentrated.
Equation number: 2: The number of the equation, also used to generate the anchor. String: suggested: Anchor id: id: The anchor id. If you set this to "my-eqn" (no quotes), the link [[#my-eqn|see my equation]] will take you to the equation. Default Defaults to "equation-" + the equation number, if that is specified.

Assume a two-stream problem having one portion of the boundary the fuel stream with fuel mass fraction =, and another portion of the boundary the oxidizer stream with oxidizer mass fraction =,. For example, if the oxidizer stream is air and the fuel stream contains only the fuel, then Y O , O = 0.232 {\displaystyle Y_{O,O}=0.232} and Y F , F ...
