I'm going to assume you mean a volume of 500cm3.
density = mass/volume = 400g/500cm3 = 0.8g/cm3
Density is mass divided by volume. This block of wood is therefore 0.75g per cubic cm.
since D=m/v... then the density of the block of wood would be mass / volume..... mass in grams divided by volume in ml.
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)
Volume cannot be 29.4 cm since that is a measure of a length, not volume. Assuming that you meant 29.4 cm3, the density is mass/volume = 25.0 g / 29.4 cm3 = 0.850 grams per cubic centimetre (to 3 dp).
There is not enough information in this question to answer it properly. However, if the density is 0.6 g/cm3 and its volume is 1.2 cm3 then you must take the density and multiply it by its volume and it will give you the answer in g. Density is measured in gm/cm3. Volume is measured in cm3 So for 1.2cm3 at a density 0.6gm/cm3 you have a mass 1.2 x 0.6 gm/cm3 x cm3 = 0.72 gm
the pice of wood has a mass of 18 grams calculate it volume and density
density is the product of mass and volume so its density will b 100 g/cm3..
Density = Mass/VOlume = 120g/200cm3 = 0.6 grams per cm3
Density is mass divided by volume. This block of wood is therefore 0.75g per cubic cm.
since D=m/v... then the density of the block of wood would be mass / volume..... mass in grams divided by volume in ml.
density is a measure of mass(weight)/ volume as the density of a specific mass increases the volume necessarily shrinks. Thus a lower density for a given mass indicates that mass has a greater volume. The wood therefor takes up more space, or volume, in this example.
density = mass ÷ volume = 600 g ÷ 30 cm3 = 20 g/cm3
Density of wood = mass/volume
Density= Volume/Mass. Therefore: (9x2x6)divided by 5.4g=Density. 108cm/5.4g=Density. 20=Density.
25/29.4 = 0.85 grams/cm3
0.3 g/cm2
Density = Mass/Volume
