KonstantinChe [14]

Answer: The density of the object is 1.10 g/ml

Explanation: Density of object = ?

Mass of object = 26.5 g

Volume of object = volume of water displaced = 24.1 ml

Putting values in above equation, we get:

$Density: \frac{26.5g}{24.1ml} = 1.10g/ml$

Thus density of the object is 1.10 g/ml
