Density

Density is mass per unit of volume. Density also shows how tightly packed in molecules are in a material and also help determine buoyancy.

What is the density of A block of wood that has a mass of 45 grams and has side lengths of Cm Cm and Cm?

It is not possible to answer the question in which the volume of the block is given as Cm Cm and Cm. Some numbers might have been useful!

How do you find the density of circle?

A circle has neither mass not volume so its density is not defined.

How do you find the density of a block of wood?

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

How would you find the density of a lump of sodium that is about 10 grams?

The volume must be determined; try the method of liquid displacement using an anhydrous mineral oil.

What is the density of a gallon of paint?

Most latex house paints have a density/weight between 9-10 pounds. It depends on the amount of resin and pigment added.

What is the density of the outercore?

the outer core is about 2300 km thick! and the inner core is solid iron 41500 degrees hot and 1250 km thick

How do you find the density and the volume of a solid when the mass is 23.07g and the length is 2.70cm and the width is 2.70cm and the thickness is 2.70cm if the density and the volume is unknown?

density = mass/volume

volume = length * height * width

2.70 * 2.70 * 2.70 = 19.683

23.07 (mass) / 19.683 = 1.17207742722146 grams per centimeter cubed

* * * * *

That degree of precision in the answer is not justified. 1.172 gms per cc is a more appropriate answer.

* * * * *

That degree of precision in the answer is justified because in some cases the difference bettween 1.17207742722146 and 1.172 could be multiplyed by that being a fraction of the number being calculated and the longer answer is actualy more acurate and the question asker can round it down if they think that for their case it would be justfied to round it down.

What is the eqyaion for density?

Density of a substance = (mass of a sample of it)/(volume of the same sample)

Density of CdS?

The density of Cadmium Sulfide (CdS) is approximately 4.82 grams per cubic centimeter at room temperature.

What is the density of the mesosphere?

100 times less than the troposphere at sea level. sea level is about 760. The mesosphere is about 0.00132

If the density of water is 1 gram per milliliter (gml) could be the density of the wooden stick to the nearest hundredth?

The density of water is 1 g/ml. If the wooden stick floats in water, its density is less than 1 g/ml. If the wooden stick sinks in water, its density is greater than 1 g/ml. To find the exact density, you would need the volume and mass of the wooden stick.

Find the density of a 7 kg solid cylinderThe cylinder is 15 cm tall and has a radius of 4 cm?

Density is mass divided by Volume The volume of a cylinder is pi*r^2*h

So the volume of your cylinder is pi*16*15. Using 3.14 for pi that means the volume is = 753.6 cm^3 Dividing 7 by 753.6 = 0.009288

When calculating the density of a mass of 52.457 grams and a volume of 13.5 centimeters cubed at the end of the answer what symbols do you write?

The density is 3.89 grams per cubic centimetre. In symbolic form, which this site will not allow, it would be gcm3 where the 3 is in superscript font.

How do you find the density of a rectangle?

Density = Mass/Volume

So for a rectangle, find its mass, then its volume (using length x height x depth).

What substance has the density of 7.8?

The substance with a density of 7.8 g/cm^3 is typically associated with metals like iron or steel, as they fall within this density range.

Which is a density dependent factor?

Food availability is a density-dependent factor because as the population size increases, competition for limited food resources also increases, leading to a decrease in individual fitness and population growth.

What is the density of a bolt?

The density of a bolt varies depending on the material it is made from. For example, a steel bolt typically has a density of around 7.85 grams per cubic centimeter, while an aluminum bolt has a density of around 2.7 grams per cubic centimeter.
