Calculate the organic carbon content of EG
Thread Content
For EG, C2H6O2, what is the organic carbon content, expressed in mol/l?
Are you asking about the carbon content in it? If it’s this, it’s very simple. Content = EG density/EG molecular weight; the unit of density is g/L
For a 0.355% EG aqueous solution, the calculated organic carbon content is 0.1145 mol/l. How was this value determined?
The density of this dilute solution is taken as 1. Calculation method: (1 L * 1000 g/L * 0.355% / 62 g/mol) * 2 = 0.1145 mol/L
Could you explain why and how it is calculated?
The concentration of this solution is very low; the effect of ethylene glycol on the solution’s density can be ignored, so the solution density is taken as that of water. The amount of ethylene glycol in 1 L of solution = (1 L * 1000 g/L * 0.335%) / 62 moles/L. Since an ethylene glycol molecule contains two carbon atoms, the amount of carbon atoms = amount of ethylene glycol * 2; dividing this value by the volume gives the carbon content.
I haven’t watched it; I don’t understand what the original poster means. But the reply from the 7th floor should be quite comprehensive
