Well it applies ABSOLUTELY.....and see this [old answer.](https://socratic.org/questions/can-you-explain-balancing-chemical-equations-in-detail#365584)

Explanation:

And so if you start with 10*g of reactant from ALL sources, AT MOST you can get 10*g product. And in practice you are not even going to get that, because losses inevitably occur upon handling.

And today we have a particle view of chemical reactivity, which insists that particles themselves have mass, and their combinations and reactions should involve addition of the requisite masses; in all instances, the masses are conserved....
