Answer:

$\boxed {\boxed {\sf d\approx5.49 \ g/cm^3}}$

Step-by-step explanation:

Density can be found by dividing the mass by the volume.

The mass of the rock is 555 grams and the volume is 101.1 cubic centimeters.

$m=555 \ g \\v= 101.1 \ cm^3$

Substitute the values into the formula.

$d=(555 \ g)/(101.1 \ cm^3)$

Divide.

$d=5.48961424 \ g/cm^3$

Let's round to the nearest hundredth to make the answer more concise.

The 9 in the thousandth place tells us to round up. In the tenth place, the 8 will become a 9.

$d\approx5.49 \ g/cm^3$

The density of the rock is about 5.49 grams per cubic centimeter.
