How do we use the law of conservation of mass when

Answer (1 of 5): When balancing chemical equations- you do not use conservation of mass at all. eg CH4 + O2 → CO2 + H2O - needs balancing. you use the idea that each type of atoim is conserved - so looking at this you can see it is not currently correct. On the LHS there are 2 O atoms and on th
