A substance has a volume of 10.0 cm3 and a mass of 89 grams. What is its density?

0.11 g/cm3

8.9 g/cm3

99 g/cm3

79 g/cm3

The question asks us to find the density of a substance which has a volume of 10 cm^3 and a mass of 89 grams. The density of a substance is its mass per volume (mass divided ba volume). We know that the formula is: D = m / V, where D is the density, m stays for the mass and V stays for the volume. D = 89 g : 10 cm^3; D = 8.9 g/cm^3. Answer: B) 8,9 g/cm^3.
