How many times more dense is lead than water?
February 01, 2009 5:08PM
It is about 11.36 times heaver that air (at room temperature). Density is measured either in kg/m3 or as a relative density compared with water (water being 1.0). Water: 998kg/m3 (r.d 1.0) Lead 11340kg/m3 (11.36)

8700 milliliters is how many pounds?
Liters, milli or otherwise, measures volume. Pounds represent weight. Unless one knows what there is 8,700 milliliters of, one cannot know what it's weight would be. T As an example, the difference between the weight of a liter of lead and a liter of water would be quite noticeable. A liter of water weighs 1 kilogram or 2.2 pounds (approximately). Therefore, 8,700 milliliters of water, which is the same as 8.7 liters of water, would weigh 19.14 pounds. (2.2 pounds times 8.7 liters) As lead is 11.4 times as dense as water, we can see that 8,700 milliliters of lead, or 8.7 liters of lead, would weigh 218.19 pounds. (25.08 pounds times 8.7 liters)
Are there solids that are less dense than liquids?
Yes, there are many. For example, anything that floats on water is less dense than liquid water. A number of solids are less dense than liquids. The most common example is ice. Ice (frozen water) is less dense than its liquid counterpart for some very specific reasons. Many other solids are less dense than liquids, as well. Using water as the liquid, you'll find that cork, wood (most kinds) and styrofoam will all float on it. As the liquid becomes more dense, the range of items that will float on it increases. Mercury, for example, is a liquid metal at room temperature. Because it is so dense, many things will float on it. Lead is one example of something that will float on liquid mercury. For a question about substances that are less dense in their solid form than those same substances in their liquid form, use the link below to the related question.

Asked in Pickles
Why do pickles float in the jar?
Any object that floats in water is less dense than water (boats are a special case; even when made of materials denser than water, they also enclose large amounts of air, which has a very low density). Although the water molecule is small, they pack close together and form a relatively dense fluid. Larger organic molecules are in many cases less dense because they are not as tightly packed. So, in pickles, there is a certain amount of molecules that are less dense than water.

What is the density of water and what is denser than it?
The density of water is dependent on the temperature. However, 4 °C, the density of water is exactly 1 gram per milliliter (1 g/mL). This is the same as saying the density is 1 kilogram per liter (1 kg/L). For a table of the density of water at several other temperatures, see the Web Link to the left of this answer. Many things are more dense than water. Almost all metals are more dense, for instance. Glass and many plastics are also more dense than water.
