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

Explanation:

The formula is density = mass÷volume

Values given are:

mass = 5.910g  and

diameter = 10.0 mm = 1cm

so, we need to find the volume first.

Volume of a sphere is (4/3)πr³

thus, V = 4.189 cm³

Density = mass ÷ volume

density = 5.910 ÷ 4.189

= 1.411 g/cm³

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
