Final answer:
The mass of the bread would be greater than the original total mass of the ingredients in the recipe.
Step-by-step explanation:
The mass of the bread would be greater than the original total mass of the ingredients in the recipe. This is because during baking, the ingredients undergo a chemical reaction and some of the mass is lost in the form of water vapor.
However, the total mass of the bread plus the water vapor released during baking would be equal to the original mass of the ingredients. This is consistent with the law of conservation of mass, which states that mass is neither created nor destroyed in a chemical reaction.
