Question

You just found a metallic object in a creek bed. From the following tests and Figure 2, determine what it is.



96.5g will balance the object. Its mass is g.

The object displaces 5 mL of water. Its volume is cm 3.

The density of the object is g/cm 3.

The object you found in the creek is

Answer 1

The mass of the object is 96.5 g.

The volume of the object is 5 cm³.

Density = mass/volume = 96.5 g/5 cm³ = 19.3 g/cm³

The density of the object is 19.3 g/cm³.

The object you found in the creek is probably a gold nugget

(density = 19.3 g/cm³).

Answer 2

Answer:

mass: 96.5 g

volume: 5 cm^3

density: 19.3 g/cm^3

The object you found in the creek is a gold nugget

Explanation:

If a mass of 96.5g will balance the object in a pair of scales, then its mass is 96.5 g.

If the object displaces 5 mL of water when you introduce it in some vessel, then its volume is 5 cm^3 (notice that mL and cm^3 are numerically equal).

The density of an object is the quotient between mass and volume, then the density of the object is: 96.5 g/5 cm^3 = 19.3 g/cm^3

From its density it can be deduced that the object is a gold nugget.
