How to Calculate the Density of a Metal Using Water Displacement Method

Calculating the Density of a Metal

To find the density of the metal, first, we calculate its mass. The mass of the stoppered flask with the metal is 144.076 g, and the mass of the empty stoppered flask is a value that was not provided in the question but is needed to proceed. Assuming this value is given, subtract it from 144.076 g to get the mass of the metal alone. Next, we calculate the metal's volume using water displacement. The total mass of the flask with the stopper, metal, and water is 162.292 g. The mass of the flask and stopper with just the metal was 144.076 g. The difference between these two masses gives the mass of the water that has been displaced by the metal, from which we can calculate volume since the density of water is 1.00 g/mL (1 g of water = 1 mL of water).

Finally, density is mass divided by volume, which can be found using these calculations.
