The two choices that MUST be applied in order to work with the law of conservation of mass are:
1. **The masses must be in a closed system.**
2. **The equation has to be balanced.**
These conditions ensure that the total mass before and after a reaction remains constant, in accordance with the law of conservation of mass. Changing subscripts or requiring coefficients greater than 1 are not necessary for this principle to apply.
