IF you knew the volume of the block and the density of the material it was made of you could calculate it mass (mass = density * volume) but it is normal to measure the mass of something using a mass balance.

Density = Mass/Volume

It is the mass of the block divided by its volume.

Divide the mass by the volume to get the density.

The block's density is 500 kg/m3

since D=m/v... then the density of the block of wood would be mass / volume..... mass in grams divided by volume in ml.

2.7gcm3

What is the density of a plastic block with a mass of 2.0 grams and a volume of 2.5cm3?

Something to determine volume (like a bucket of water or a ruler), and a balance to determine mass. Divide the mass of the block by its volume to find the density of the block.

An 8 cc block with a mass of 12.9 grams has a density of 12.9/8 = 1.6125 g/cc

you weigh the block on a balance get its mass if it is a regular shape block so the volume should be length * weadth * breadth (side * side * side) the density = mass / volume

The block has a density of 4 g/mL

Density is mass divided by volume. This block of wood is therefore 0.75g per cubic cm.

Density of wood = mass/volume

Volume of block 6X5X2 cubic centimeters = 60cc Density is mass/volume e.g. g/cc So density of this block is 180/60 = 3 g/cc (3 g cm-3)

Yes. Density is the measure of the substance, quite apart from size or mass. It therefore remains constant in whatever the size or mass of the iron block.

density is the product of mass and volume so its density will b 100 g/cm3..

Density = Mass/Volume = 13.6 g/cm3

Density = mass/volumeFor the cube of water having a mass of 1g:Volume of a cube of water measuring 1cm X 1cm X 1cm =1cm3.Density = 1g/1cm3 = 1g/cm3For the block of "plasting" having a mass of 4g:Volume of the block of plasting measuring 2cm X 3cm X 1cm = 6cm3.Density = 4g/6cm3 = 0.7g/cm3I will let you decide which has the greatest density.

Density means mass per unit volume. Hence, mass of a body divided by it's volume will give us it's density. Here mass = 4g, volume= 5cm3 So, density = mass/volume =4g/5cm3 =0.8g/cm3 This is the average density of the wooden block. The density of block whole throughout it's body may not always be equal to this value. Some portions of block can be more dense and some less dense. But the average density of any body having mass= 4g and volume = 5cm3 is always 0.8g/cm3 .

The units for density are incorrect. If the density of a block of wood is 0.5 g/cm3 then the volume of a 27 g block would be 27/0.5 cm3 = 54 cm3

The volume will be reduced to a half of its original value. If the mass is (approximately) evenly distributed throughout the wooden block then the mass will also reduce to a half of its original value and the density will not change.

The block has a density of 500 kg/m3

yes (that's a heavy necklace)

Density = Mass/Volume = 2.7 grams per cm3
