Calculate the mass of 5000 spherical lead shots each of the diameter 0.4 cm if the mass of 1 cm(cube) of lead is 11.3 g.

Question

5000 SPHERICAL LEAS SHOTS OF EACH DIAMETER 0.4 CM

Answer 1

We need a couple of things here.

 

First the Volume of a sphere = 4/3 πr³

A 0.4 cm diameter sphere has a volume of 4/3 π0.2³ = 0.335 cm³

We know that 1 cm³ of lead has a mass of 11.3g, 

 

We have 5000 of these lead shots with a total volume of 

5000 x 0.335 = 167.5 cm³

 

167.5 x 11.3 = 1892.4 g
