Question

what is different about the law of conservation of matter compared to \loc\ mass?
law of conservation of mass deals with grams instead of atoms
law of conservation of mass deals with atoms instead of density
law of conservation of mass deals with atoms instead of grams
law of conservation of mass deals with pepsi instead of coke a cola

Explanation:

The law of conservation of matter and law of conservation of mass are related concepts in chemistry. The law of conservation of mass focuses on the quantity of mass (measured in grams etc.) being constant in a chemical reaction, while the law of conservation of matter is more general and can consider atoms and their conservation. The correct distinction is that the law of conservation of mass deals with grams (a measure of mass) rather than atoms (which are related to the law of conservation of matter in terms of their conservation in reactions). The other options are incorrect as density is not the differentiating factor, and the last option about Pepsi and Coke - a - cola is completely off - topic.

Answer:

law of conservation of mass deals with grams instead of atoms
