what mass of oxygen is required to react completely with 24g of CH4 in the following reaction?
CH4 + 2O2 = CO2 + 2 H2O
Ive got the answer 12g of O please tell me if Im wrong.

anonymous · Answer

coefficient of CH4 is 1 ok
24/16=n
3/2=n
 now u see for the coefficeint of 1 there is 3/2mole
then for coefficent of 2 there will be 3mole
now 3=mass of oxygen/32
96gm=mass of oxygen

anonymous · Answer

use stoichiometery coefficient thing here ok

anonymous · Answer

16 g needs 64 g oxygen
1 g CO2 needs 4 gram oxyeg
24 gm needs 96 gm Oxygen 

Im a fool!!! Its done
