Would two pieces of brass that are in the exact same shape and size have the same mass?

No, two pieces of brass that are in the exact same shape and size may not have the same mass. The mass of an object depends on its density, which is the amount of mass per unit volume.

To determine if two pieces of brass have the same mass, you would need to weigh them. You can use a balance or a scale to measure the mass of each piece. It is important to note that even though the shape and size of the brass pieces are the same, there may be variations in their composition or density, which can result in different masses.
