The given dimensions can be thought of a length, width, and height; so multiply them together to get volume: 2.00x5.50x1.25=12.5cm3. You're given its mass (37.1g), so now divide mass by volume to get density:
D=37.1/12.5=2.97g/cm3.
density = mass / volume, and volume = length * width * height, so
density = mass / (length * width * height)
= 20 g / (5 cm * 2 cm * 10 cm)
= 20/100 g/cm3
= 0.2 g/cm3
The measurement unit for volume is not a centimetre and so the volume cannot be W cm and, in that respect, the question is flawed. If you meant W cubic centimetres, then the density is 525/W grams per cubic centimetre.
density = mass/volume,so the density of your metal is:25/10 = 2.5g/cm3 (grams per cm cubed)
Mass
Use the expression, density = mass/ volume. So density = 150/115 = 1.304 g/cm3
This depends on: the volume of the cube, the density of the metal, the atomic weight of the metal.
The volume of displaced water for a metal cylinder with a volume of 50cm3 is: 13,210 US gallons of water or 11,000 UK gallons of water.
The metal block's density is about 13.636 g/cm3
Density = Mass/Volume = 13.6 g/cm3
Just divide the mass by the volume.
Density is mass divided by volume. D = (750g/55cm3) D = 13.63636 g/cm3

what is the unit for the mass density = mass over volume volume= length*height*width check the units whether you need to convert or no and then complete it
Density is the mass of the object divided by its volume. By this principle, to determine the density of a metal, place the metal onto a scale to measure its mass. After this, place the metal into a beaker of water and measure the volume change in the beaker. Divide the mass by the volume and you get the density.
Density = g / Cm Assuming g is in a unit of mass, and Cm is in a unit of volume, If these are not the units of the quantities given then the result will not be density, instead it will be gibberish! The units of the quantities going into an equation are more important than the values.
The measurement unit for volume is not a centimetre and so the volume cannot be W cm and, in that respect, the question is flawed. If you meant W cubic centimetres, then the density is 525/W grams per cubic centimetre.
Air bubbles would make the volume you read in the measuring cylinder increase from the actual volume of theliquid. so when you add in the metal, there would be an increase in the volume of the metal than it really is. the mass of the metal cannot be affected by air bubble because this is the amount of matter in the metal. This increase in volume causes the density of the metal to reduce from its original value. since mass is constant, density is inversely proportional to volume. As volume increases, density decreases.hope that was helpful.
The density of the metal will remain the same. However because the volume of the object has been reduced the overall density will increase
