Question

radius of iron square is 0.21 CM if density of iron is 7.80 g lcc calculate is mass

Answer 1

Here is ur answer........

Answer 2

Hey!

____________________

Radius of iron sphere = 0.21 cm
Volume of iron sphere = 4/3 πr^3
Volume = 0.0388 cm^3

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

We know,

Density = Mass/Volume
7.8 = Mass/0.0388
Mass= 3.02 g/cm^3 [Approx.]
