you need to know how to calculate the final concentration. While you can use a dilution ratio calculator or something similar (see Resources) to find this out, it’s much better to learn the math itself, so you can do it yourself with the calculator on your ...
I know how to find the lower flammability limit (LFL) and I know what my expected room temperatures will be. However, I do not know how to calculate the relevant concentration of the flammable materials. I'm guessing that this calculation is within the domain of mechanical design, and that...
Plug in the molecular values for the density equation. Multiple both sides of the equation by v over 1. This removes the fraction and results in the equation v x p = m. Divide both sides by p (rho). (vp= m is equal to v = m / p). The resulting value for v is the volume o...
Sulfuric acid (2.5M) My question is, which one am I supposed to use to figure out the concentration? The products/rectants? The actual chemicals used or equation of reaction? Do I add all the chemicals/ions used and use a single concentration? And how exactly should I calculate the conce...
- how to calculate pH of a solution containing borax, or any other substance without a known pka (and, if possible, why aren't they known), Without known Ka - impossible.It is not like borax doesn't have known Ka values, more like it has several (stepwise dissociation) so in a gene...
In order to accurately calculate the mass of a material that is sublimating, you need to take into account the changing surface area over time. This can be done by using integrals, as you have mentioned. The equation you have provided is a good starting point, but it may not giv...
How to calculate concentration of NaOH in titration? Acid-Base Titration: Titration is an analytical technique used in chemistry that allows for the determination of an unknown quantity or a concentration of an analyte using a known concentration of a titrant. A titrant is a solution that reacts...
