Question

A rock with a mass of 537 g is added to 50.1 ml of water. The water level rises to a volume of 77.1 ml. What is the density of the rock

Answer 1

537/(77.1-50.1) g/cc

Answer 2

Answer:

Explanation:

By definition,

ρ

density

=

Mass

Volume

, and thus it typically has the units

g

⋅

m

L

−

1

; in this example your

7.5

⋅

g

mass displaces a

5.0

⋅

m

L

of water, and thus........

ρ

=

7.5

⋅

g

(

30.1

−

25.1

)

⋅

L

=
