Answer:
[tex]\boxed {\tt d=2.5 \ g/cm^3}[/tex]
Explanation:
The density of an object can be found by dividing the mass by the volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the pebble is 35 grams.
The volume of the pebble is 14 cubic centimeters.
[tex]m= 35 \ g\\v= 14 \ cm^3[/tex]
Substitute the values into the formula.
[tex]d=\frac{35 \ g}{14 \ cm^3}[/tex]
Divide.
[tex]d=2.5 \ g/cm^3[/tex]
The density of the pebble is 2.5 grams per cubic centimeters.
