err, yes, because: bottle mass + soda mass > bottle mass

mass of Na2CO3 with 10H2O of crystallisation is 286g
About a kilogram.
The can of soda has a density of about 0.774 g/mL
they don't if in a sealed container
The mass decrease occurs because during the reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid), carbon dioxide gas is produced, which escapes into the air. This gas escaping means that the total mass of the system (baking soda + vinegar) is reduced, leading to a decrease in mass when compared to the initial sum of the individual masses of baking soda and vinegar.
The density of a full can of soda changes when it is empty because density is defined as mass per unit volume. When the can is full, it contains both the liquid soda and carbon dioxide gas, resulting in a higher mass and a specific volume. Once the soda is consumed and the can is empty, the mass decreases significantly while the volume remains largely unchanged, leading to a lower density. Additionally, the absence of the liquid means there is less mass in the same volume of the can.

Mass isn't lost, it just escapes as a gas
