a 2.52 g. sample of an unkown compound conraining CHONS was burned in excess 02 to yield 4.23g of co2 and 1.91g of H20. A second sample of unknown mass 4.12g burn yield 2.11g of So3 along with other products. 3rd sample mass 5.66g burn yield 2.27g HNO3 w/ other products. find empirical formula of unknown cmpound. (%O determine by finding other percentage of elements and subtract from 100%)
okay. I don't even know where to start. I didn't relize we have to find % composition to find empiriccal formula. A guide please and thank you
