Question

The density of osmium, which is the densest metal, is 22.57 g/cm3. What is the mass in kg of a block of osmium that measures 1.00 cm x 4.00 cm x 2.50 cm?

Answer 1

0.2257kg

Step-by-step explanation:

Using the formula density= mass/ volume

• density=22.57g/cm³
• volume=1*4*2.5cm³= 10cm³
• mass is unknown

22.57g/cm³=mass/10cm³

• cross multiply

mass = 22.57g/cm³*10cm

=225.7g

but in kg

• convert to kg
• 225.7/1000

= 0.2257kg
