AI Thread Summary
To determine the formula of an ionic compound using only the weight of the sample and its conductivity compared to a standard, one must first calculate the molarity of the sample based on its weight. This involves converting the weight into moles using the molar mass of the compound, which may require reference to tables for known ionic compounds. Conductivity measurements can help identify the compound by comparing the sample's conductivity to that of known standards, as ionic compounds with different compositions will exhibit varying conductivity levels. The combination of these two methods—weight analysis and conductivity comparison—can narrow down the possible formulas of the ionic compound.

How to find the formula of an ionic compound if all you have is...

the weight of the sample and the conductivity of the given sample and of a conductivity standard already found?

Ive been stuck on this for hours X)

Please elaborate. You probably have to check in tables, or your sample is just one of a few possible. Or both.

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
