Empirical Formula from Experimental Data

Показать описание

How to calculate the empirical formula of a compound. All you need to do is find some way to decompose the compound into its constituent elements, measure the masses of those elements, convert those masses into moles, and then find the greatest common factor of the molar amounts of the elements.

Thanks for watching! 😀

really way better than my chem teacher... he is just like divide this into this and when you get that divide or multiply by that.. thanks alot

Thanks a bunch, you simplified the solving method a lot. (and it is the first time for me to know the way of dividing by half or 1 third or quarter. (You have been a great help to me.) )

Yea, that's what I was thinking before I saw him divide by the 1/2. You can do it that way I've learned (just from myself), however you can also do it his way (dividing by smaller and smaller fractions).

i have never been more confused in my life

What is the empirical formula for a compound that contains 31.9 g of Mg and 27.1 g of P?

How do you get 56.18? Putting it into several different calculators gets me 55.75

Don't you mean 1/100, not 1/10, to consider it to be a whole number?
