emperical formulas
(1/1)
hardeep:
well I have to find the empirical formula for the following question
after decomposing a compound, it was found to contain 4.68 g of carbon and 0.78 g of hydrogen, what is the imperical formula
is the answer C[size=0]2[/size]H? ???
Winga:
It should be CH2.
lemonoman:
Should it Winga? Should it really? ;)
hardeep, check that answer, and make sure you know where the numbers are coming from. Just in case. I don't like to throw red herrings, but this WILL be on an exam at some point, no matter what course you're taking. Know it.
Have a nice day, and good luck :)
xiankai:
the decomposition eraction was basically
CxHy --> xC + yH.
by converting given data to moles, and arriving at the the ratio, the answe should be easy. i obtained CH2 like Winga, tho.
hardeep:
yes i have noticed where I made the mistake i stupidly mixed up the numbers, next time I will write down every last step thanks for everyones time :)
