An aluminum engine block has a volume of 4.77 L and a mass of 12.88 kg. What is the density of the aluminum in grams per cubic centimeter?
Answer (2)
1 l = 1 d m 3 = 10 c m ∗ 10 c m ∗ 10 c m = 1000 c m 3 This means that the volume of block is : V = 4 , 77 ∗ 1000 c m 3 = 4770 c m 3
1 k g = 1000 g This means that the mass of block is: M = 12 , 88 ∗ 1000 g = 12880 g The density of the aluminum can be counted with equation: ς = V M = 4770 12880 = 2 , 7 c m 3 g
The density of the aluminum engine block is approximately 2.70 g/cm³. This is calculated by converting the volume from liters to cubic centimeters and the mass from kilograms to grams, then using the density formula. The final result is obtained using the equivalent mass and volume values.
