Question

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

Answer 1

Explanation:

density = mass / volume

mass = 1 kg = 1000 gm

volume = 4 × 4 × Side

ATQ,

22.57 = 1000 / (4 × 4 × side)

side = 1000 / 16 × 22.57

side = 2.76 cm

Answer 2

Given:

density=22.57g/cm3

mass=1.00kg convert it into g

i.e. mass=1000g

volume = length x width x height

             =4 x 4 x side

mass = volume x density

volume = mass/density

4 x 4 x side=1000/22.57

16 side =44.30

side = 44.30/16

side=2.76cm
