Question

calculate relative density of iron if density of water is 10³kg/m³ and density of iron is 7.85×10³kg/m³​

Answer 1

Answer:

relative density = ?

density of water = 10³kg/m³

density of iron = 7.85 × 10³ kg/m³

relative density= density of substance÷density of water

r.d= 7.85×1000/1000

r.d=7.85.
