Question

How many grams of iron (density = 7. 87 g/ml ) would occupy the same volume as 96. 4 g of aluminum (density = 2. 70 g/ml)?.

1 Answer

  • Explanation:

    density = mass / volume

    96.4 g of aluminum / volume = 2.7

    therefore,

    96.4 = 2.7 × volume

    volume = 96.4 / 2.7 = 35.7037037... ml

    back to iron :

    7.87 = mass / 35.7037037...

    mass = 7.87 × 35.7037037... = 280.9881481... g

    it would be 280.9881481... g of iron in the same volume.
