The density of osmium is 22.57g/cm3. If a 1.00kg rectangular block of osmium has two dimensions of 4.00cmx4.00cm, calculate the third dimension of the block.

Answer 1

mass = volume x density
mass in grams, volume in cc and density in g/cc.
You have mass (1000 g) and density (22.57 g/cc). Calculate volume. Then remember volume = length x width x height. You have length and width, calculate height.
