If the object shown has a mass of 80g, what is the density?

Vilka [71]

Answer:

C. 1.23 g/ml

Explanation:

$Density = \frac{Mass}{Volume}$

Mass of rock = 80g

Volume of rock = final fluid volume - initial fluid volume

Volume of rock = 265 cm³ - 200 cm³ = 65 cm³

$Density = \frac{80g}{65 cm^3}$

$Density = 1.23 g/cm^3$

1 cm³ = 1 ml

Therefore, density of the object = 1.23 g/ml
