Question

A spherical ball has a diameter of 1.00 inch and a mass of 2.00grams. Will the ball float or sink in water? Remember that if the balls's density is greater than 1.00 g?mL (the density of water), the ball will sink.

Answer 1

volume sphere is V = (4/3)*pi*r^3
density = mass/volume

Answer 2

so:

v= 4/3*3.14*0.5^3= 0.52

then take 2.00g/ 0.52 = 3.85g (ball will sink)
