Law of Conservation of Mass Word Problems

Law conservation mass word problems.
In the video, I show two types of law of conservation word problems. The first problem involves counting atoms and the second problem involves finding the mass of the reactants and the products.
Example problem:
How much oxygen would add with 36g of carbon to give 136g of carbon dioxide?

Hello professor, can I ask you a simple question : imagine if you put a quantity( amount) of water in a glass ( simple glass), can you put this water in another glass ( I mean : to the extent of 100% of quantity of water ), can you carry this amount of water( 100% of amount) in another glass ( to put all quantity of water in another glass( without losing any drop or molecule of water during the transportation), can you do that ?
I think If you would try it you wouldn't, if you do that then your law( or equation) would be correct. Same thing happens when water condenses, is impossible to transport( to be transported)all amount of water ( all molecules) during the cycle of condensation, ( during the rain formation ), it mean : the matter is losing during the cycles
verify the physics pls,
