I don't believe there is a way to find the mass of an object knowing only the diameter of the object. If you had the volume, or some other measurements sure. the best bet would be just to weigh it, or find the volume using the principles of displacement.
A typical marble is around 4 or 5 grams so 90-100 of them will be about 1 pound. The average glass marble for playing with are about 14-16mm in width.
Why the mass? Volume sphere = 4/3*pi*r^3 r = 1.5 cm/2 = 0.75 cm V = 4/3* pi *(0.75)^3 = 1.8 cubic centimeters

The equation for determining the circumference of a circle is circumference = pi x diameter. So if the diameter is 5, then the circumference is pi * 5 = 15.71
Assuming a diameter of 5 inches.The area of this circle is: 19.63
Denisty = mass/volume. 13/5 and then convert your units as need be.
It would vary because marbles come in several different sizes. They also come in a variety of materials like glass, agate, flint, etc. The denser the material the more mass it would have. Therefor, a 3/4" marble of flint would have more mass than one the same size made of glass.

Devin Marble is 5' 7".
Rotated about a line on the surface ? I = Mass * radius2 . Rotated about a line through the centre : I = (2 * mass * radius2) / 5
An electronic balance.
Marble Rocks range from 4 to 5 on the Mohs scale
diameter = 5/pi
The probability of choosing a blue marble is 5 in 15 or 1 in 3. The probability of then choosing a green marble is 5 in 14. (One is missing) Multiply the two probabilities and you get 5 in 42.(P = 0.1190... about 12%).
