Answer:
9.368g/mL
Step-by-step explanation:
The density is defined as the mass of a compound in a determined volume.
Based on Archimedes' law, the volume of the piece of metal is the difference between the volume of the water + the inmersed piece - the original volume of water. That is:
Volume of the metal:
257.5mL - 229.0mL = 28.5mL
As the mass of the metal is 267.0g; its density is:
Density:
267.0g / 28.5mL =
9.368g/mL
