If two perfect spheres of different sizes have the same mass, then the larger ball has a lower density and the smaller ball has a higher density. This is because density is the amount of mass in a given volume, and density is obviously higher if there is a smaller volume for a given amount of mass.
Bulk density is to find in Wikipedia: http://en.wikipedia.org/wiki/Bulk_density Real density is here to find: http://www.istone.ntua.gr/Training_courses/wp1/real_density.html Apparent density is here to find: http://www.bulk-online.com/Forum/showthread.php?threadid=6440
because of the density of oxygen.
Why not ? The density is (mass) divided by (volume). As long as the answer tothe division is the same, the densities are the same.Here's a simple example:Take one brand new golf ball. It has a mass, it has a volume, and (mass) / (volume)is the density of the golf ball.Now take a carton of 24 of the same identical golf balls. The whole load of themhas 24 times as much mass as the single ball, and it also has 24 times as muchvolume as the single ball. When you divide the total mass by the total volume youget exactly the same number you got for the single ball. 24 of them all togetherhave the same density as one of them has, even though their mass is differentfrom a single ball and their volume is different too.The density doesn't depend on the mass or the volume. It only depends on theanswer to the division of one by the other. That's why it's such a useful number.It totally does not depend on the size of the sample. The density of golf ballscan be directly and precisely compared to the density of dust particles, boulders,battleships, and asteroids.

Density is mass divided by volume. If the density is greater and the volume is the same then the mass must also be greater for the same size balls.
balls!

Certain WEIGHTS of bowling balls float. Bowling balls have a volume of 6250 cm3. An equal amount of water would weigh 6.25 kilograms. A bowling ball that weighs less than 6.25 kilograms--8-pound, 10-pound and 12-pound balls--will float. 14-pound and 16-pound balls, having a density higher than 6.25 kilograms, will not float.
Packing factor is a dimensionless ratio that describes the amount of volume that a substance takes up in a particular volume. For example, if you have a box and you fill it with balls, the volume of the box is taken up by the balls and by the space in between the balls. The packing factor would be (volume of the balls)/(volume of the box). Packing factor is, among other things, relevant to the arrangement of atoms in different crystallographic structures.
Ten-pin bowling balls usually weigh from about 6 pounds (around 2800 grams) to 16 pounds (about 7200 grams) There are no bowling balls that weigh 200 grams (though such a ball would be leagal as there is no minimum weight) but if there were, the mass of the ball divided by the volume of the ball gives the density. The volume of a standard bowling ball is about 5500 cubic centimeters (I assumed a circumference of 27 inches and calculated from that) 200 / 5500 = 0.036 g/cm3 Compare to the density of air = 0,0012 g/cm3
The density of Diet Coke is 1.0, the same as water.
Out of those substances, mercury has the greatest density. So for the same volume, mercury will be the heaviest and carry the most inertia.
because of the density of oxygen.
