Step 1

All the calculations are done for trial 1 only. The density of water (d) is calculated using the mass of water (m) and the volume of the flask (V) given in the table as follows:

Step 2

The mass of stoppered flask (mf), the mass of metal (mm), and the mass of ‘flask + metal + water’ (mfmw) is 29.397 g, 29.039 g, and 77.791 g, respectively. The mass of water (mw) surrounding the metal is calculated as follows:

Step 3

The volume of water (Vw) surrounding the metal...
