------------------------------------------------ Density is the ratio of mass to volume. An object with a volume of 25 cubic centimeters (cm³) has a mass of 125 grams (g). What is the density, in g/cm³, of the object?

A. 5
B. 25
C. 100
D. 3125

Answer :

The density is a ratio, defined as

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

replace in the ratio of density

[tex]\rho=\frac{125g}{25\operatorname{cm}3}[/tex]

the density will be

[tex]\rho=\frac{5g}{\operatorname{cm}3}[/tex]
