How to Convert Mass Fraction to Mole Fraction Using CO2?

AI Thread Summary
To convert mass fraction to mole fraction, the molecular weight is essential. The process involves calculating the mass of each component in a mixture and then determining the number of moles based on their molecular weights. For example, in carbon dioxide (CO2), the mass fraction of carbon (C) can be calculated by taking the mass of carbon in one mole of CO2, which is approximately 12 g, and dividing it by the total mass of CO2, around 44 g. This gives a mass fraction of carbon. To find the mole fraction, the number of moles of carbon is calculated using its molecular weight, and this is then divided by the total number of moles of all components in CO2 (1 mole of carbon and 2 moles of oxygen). This method effectively converts mass fraction to mole fraction using molecular weights.

You can try using an example like CO2
Check mass fraction of C with total mass in one mole of CO2 and then check moles of carbon in total moles of the elements in one mole of CO2.

Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...

Engineers slash iridium use in electrolyzer catalyst by 80%, boosting path to affordable green hydrogen https://news.rice.edu/news/2025/engineers-slash-iridium-use-electrolyzer-catalyst-80-boosting-path-affordable-green Ruthenium is also fairly expensive (a year ago it was about $490/ troy oz, but has nearly doubled in price over the past year, now about $910/ troy oz). I tracks prices of Pt, Pd, Ru, Ir and Ru. Of the 5 metals, rhodium (Rh) is the most expensive. A year ago, Rh and Ir...
