A rock has a mass of 450 grams and a volume of 75 cubic centimeters. After placing the rock in water, the water level rises by 25 milliliters. Calculate the density of the rock.
18g/m³
450g/25mL
The volume of the rock is given as 75 cubic centimeters (since 1 milliliter = 1 cubic centimeter, the water displacement of 25 mL equals 25 cubic centimeters).
