Question

Below is a data table from an experiment in which scoop of baking soda is added to vinegar in a beaker, producing a solution that fizzes and releases gas bubbles. The total mass of the substances, the beaker, and the measuring scoop were recorded before and after the baking soda was added to the test tube of water. If matters is always conserved, how do you explain these results?
