Answer:

[tex]\boxed{\tt d=5g/cm^3}[/tex]

Explanation:

The density of a substance can be found using the following formula.

[tex]d=\frac{m}{v}[/tex]

where [tex]m[/tex] is the mass and [tex]v[/tex] is the volume.

The mass of this substance is 90 grams and the volume is 18 cubic centimeters.

[tex]m= 90 g \\v= 18 cm^3[/tex]

Substitute the values into the formula.

[tex]d=\frac{90 g}{18 cm^3}[/tex]

Divide 90 grams by 18 cubic centimeters.

[tex]d=5 g/cm^3[/tex]

The density of the substance is 5 grams per cubic centimeter.
