Density = Mass/Volume = 25.0/28.7 = 0.871 units of mass per units of volume.
Density of wood = mass/volume
The volume of the piece of wood is (10 x 5 x 3) = 150 cubic cm. In order to find its density, you also have to know its mass. When you have that, divide it by 150 cm3, and the answer is the density.
Density = Mass/VOlume = 120g/200cm3 = 0.6 grams per cm3
d=m/v d=(25g)/(5cm3 ) d=5g/cm3
This density is 0,8 g/cm3.
The wood is "lighter" (weighs less; has less mass) than the iron because of it's density. Iron has a greater density than wood, and density is defined as mass/volume, so having the same volume (size), the iron will have a greater mass.
Density of wood = mass/volume
You times the length by the width by the height to find volume. To find the density do mass divided by volume.
0.3 g/cm2
Density = Mass/Volume
the pice of wood has a mass of 18 grams calculate it volume and density
a gram is a measurement of mas, whereas a tablespoon is one of volume. the conversion factor is dependent on the substance's density, the amount of mass in an amount of volume ie, a piece of lead would have a higher density than a piece of wood because more mass can fit into the same amount of volume. Density=Mass/Volume
25/29.4 = 0.85 grams/cm3
Density = mass/volume = 75g/1500 cm3 = 1/200 g/cm3 = 0.050 g/cm3That value is half of common balsa wood density (there are other woods that are less dense but your example is rater extreme)
The larger piece will probably have more mass than the smaller one. But if the wood is of the same type and "all things are equal" as regards moisture content, sap content, etc., the density of both pieces of wood will be the same. Density does not depend on the size of a sample. Density is mass per unit of volume. If a large gold nugget and a small gold nugget are compared, the larger nugget will have more mass, but both nuggets will have the same density.
density = m/v density = 7.35g / 8.20 ml = 0.90 g/ml
since D=m/v... then the density of the block of wood would be mass / volume..... mass in grams divided by volume in ml.
