Answer:
[tex]\boxed {\boxed {\sf d= 5 \ g/cm^3}}[/tex]
Explanation:
Density can be found by dividing the mass by the volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the quartz is 30 grams and the volume is 6 cubic centimeters.
[tex]m=30 \ g \\v= 6 \ cm^3[/tex]
Substitute the values into the formula.
[tex]d=\frac{30 \ g}{6 \ cm^3}[/tex]
Divide.
[tex]d= 5 \ g/cm^3[/tex]
The density of this piece of quartz is 5 grams per cubic centimeter.
