The mass a 50cm3 density bottle is 10.0g when empty and 60.0g when filled with copper turnings upto a
certain level. Some water is added into the bottle until it is full. The mass of the bottle and its contents is found to be 90.0g. Determine the density of the copper turnings.

Moraa
Mass of copper turnings= 60.0 – 10.0= 50.0g
Mass of water added= 90.0 – 60.0= 30.0g
Since ? of water= 1gcm-3
The volume of water added= 30.0/1 = 30cm3
Therefore, the volume copper turnings=50 – 30= 20cm3.
Hence density of copper turnings=50g/20cm3= 2.5gcm-3.
