Topic: experiment: determine empirical formula (Read 7964 times) From the experiment, i used 0.490g metal (Mg) to combust with Oxygen to form a product 0.912g. 1. when i calculate the % oxygen, 0.422/0.912 x 100%=46.3% is that correct? 2. Then i caluclate the mole of oxygen 46.3g...
those resources don't really answer the question I'm asking. I can't find out why the structural formula and chemical formula don't have the same number carbons and hydrogens, but when I added both sides of the structural formula they do add up. CH2O2C6H3CH2CH=CH2: Left side has a...
