what information are you given?

umlika · Answer

emperical formula is calculated just by the lowest ratios of any reaction :
suppose you have C6H12O6 so it's molecular formula would be 6:12:6 BUT 
it's emperical formula would be 1:2:1

nikato · Answer

wait. im just gonna check quickly

nikato · Answer

ok. its correct. to make it easier. i think we should just round to the 4th digit after the decimal. so

C-0.1435
H-0.2861
O-0.0287

now divide each by the smallest one which is pxygen

anonymous · Answer

C-5mol
H-10mol
O-1mol

anonymous · Answer
