Question

raiders of anion is there is 0.1 CM if density of iron is 7.80 g/ cc
calculated mass

Answer 1

Hey!

____________________

Radius of raider = 0.1 cm
Volume of iron sphere = 4/3 πr^3
Volume = 0.004 cm^3

Density of iron sphere = 7.8 g/cm^3
Mass =?

We know,

Density = Mass/Volume
Mass= 7.8× 0.004
Mass= 0.0312 g/cm^3
