Question

A lead ball has a mass of 5.910 g and a diameter of 10.0 mm. What is the density of lead in grams per cubic centimeter? the volume of a sphere equals 4pr^3/3, where p is 3.14, and r is the radius

Answer 1

Answer:

Density = 11.294g/cm³

Explanation:

Mass of the ball (m) = 5.910g

Diameter of the ball = 10.0mm

Radius r = 10.0/2 =5.0mm = 0.5cm

Volume of a sphere V = (4pr3)/3

V = 4*3.14*(0.5*0.5*0.5)/3 = V =1.570/3

V = 0.5233cm³

V = 0.5233cm³

Density = mass/volume

Density = 5.910/0.5233

Density = 11.2937g/cm³

Density = 11.294g/cm³
