Density

Notes

Air 0.00125  
Amber 1.25-1.55 fossil resin
Apples 0.64  
Ashes 0.66 Random tidbit: the ashes of the average cremated person weigh five pounds. (I originally listed "nine pounds" based on a web page somewhere, but further research suggested that five pounds was closer to the truth. One source claimed that ashes usually weigh approximately 3% of body weight, which also supports 5 lbs as an average figure).
Asphalt, Crushed 0.72  
Barley 0.61  
Beans, cocoa 0.59  
Beeswax 0.96  
Bone 1.7-2.0  
Bone, dry powdered 0.88  
Brick 2 quite variable, obviously
Butter 0.87  
Camphor 1  
Cement, hardened 2.7-3.05  
Charcoal 0.21  
Cork 0.249  
Flesh, Human 0.99-1.07 This is the average density of a human body with breath exhaled (density drops to 56-62 lbs/cu foot if you inhale). Lower figures reflect relatively more body fat (which is lighter than bone and muscle).
Flour, Wheat 0.59  
Glass 2.4-2.8  
Gum Arabic 1.3-1.4 a plant derivative used in glues, inks, confectionery, and pharmaceuticals
Ice, crushed 0.59  
Ice, solid 0.92 This is the density of pure ice (917 kilograms per cubic metre at 0 C and atmospheric pressure). Most naturally occurring ice is less dense due to pockets of air, ranging from around 53 lbs/cubic foot on up.
