In our facility we are using an analyzer that measures %Weight concentration of two solvents (%Wt of X in water solution, and %Wt of Y in the same solution) simultaniously and the temperature.
An example existing output:
- NaOH in solution: %8 Wt
- NaCl in solution: %12 Wt
- T = 20 Celcius
An example desired output:
- NaOH in solution: 15 g/l
- NaCl in solution: 26 g/l
In order to make the measurements useful I need to output them in the units of g/L. Can someone explain how can I go from %Weight to g/L? I couldn't come up with a formula to solve it. I would appreciate your help.
I simply copied your topic header into Google and came up with this site.
I always mess up when I try to convert something like that.
one liter H2O = 999g / 20 DegC
8% Wt-> 80 grams per liter of water
12% Wt -> 120 grams per liter of water
a rough estimate for the mixture
Wt(NaOH) =100*80(g/L)*density NaOH(est. 2.130)=170.4 g
Wt(NaCl)= 100*120(g/L)*density NaCl(est. 2.163)=259.6 g
Wt%(NaOH) = 17 % of 1000g Mixture
Wt%(NaCl) = 26 % of 1000g Mixture
the actual data is usually tabulated
Thanks a lot for the detailed answer. I have a question:
1) You wrote: ">8% Wt-> 80 grams per liter of water". In my understanding, %8Wt=Weight of NaOH/(Weight of H20 +Weight of NaOH+Weight of NaCl). But in your formulation, %Wt(NaOH)=Weight of NaOH/Weight of H20, what I believe is incorrect. I may be wrong, but according to my internet research my formula should be the correct one. Waiting for your comments.
