The mass density ρ of an object may be found by
dividing its mass M by its volume V
. Sphere: V = (4/3) π R
3
where R is the radius of the sphere. Cylinder: V = π R
2
L where R is the radius of its base and L the length of it.
What is the density of a ball bearing?
| Chrome Steel Chemical Analysis | Sulfur 0.025% Max. | Chromium 1.30 – 1.60% | Ferrite Balance |

How do you find density of a sphere?
- Formula. D = m / (4/3*pi*r^3)
- Mass.
- Radius.
How are density determined?
Density, mass of a unit volume of a material substance. The formula for density is
d = M/V
, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre.
How do you find the density of granular sodium chloride?
density of NaCl = ( 58.45 × 4 ) ÷ ( 0.563

Is density the same as volume?
Introduction: Volume – How much space an object or substance takes up. … Density – How much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). The amount of mass per unit of volume.
What is the density of cylinder?
The density of our cylinder is
5.31 pounds per cubic foot
. The units for mass were pounds and the units for volume were cubic feet. Therefore, the units for density will be pounds per cubic foot.
What is the density symbol?
The symbol for density is
the Greek letter rho
, What is the density of a material if 450 cm
3
of it has a mass of 200 g?
What is difference between density and relative density?
The expression for the density of a substance can be given as: mass of substance volume of substancemass of substance volume of substance. On the other hand, the relative density of a substance is defined as
the ratio between the density of that substance and the density of the water
.
What is the tool used to measure density?
Hydrometer
, device for measuring some characteristics of a liquid, such as its density (weight per unit volume) or specific gravity (weight per unit volume compared with water).
What is the unit of density?
Density is commonly expressed in units of
grams per cubic centimetre
. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre. Density can also be expressed as kilograms per cubic metre (in metre-kilogram-second or SI units).
How do you find the density of sugar?
Divide the mass of the sugar water by its volume to determine its density
. The calculation for the example looks like this: Density of sugar water = 53 grams / 50 milliliters = 1.06 grams per milliliter.
What is the density of water?
The density of water is
roughly 1 gram per milliliter
but, this changes with temperature or if there are substances dissolved in it. Ice is less dense than liquid water which is why your ice cubes float in your glass. As you might expect, water density is an important water measurement.
What is difference between mass and volume?
Volume – How much space an
object
or substance takes up. Mass – Measurement of the amount of matter in an object or substance.
What are the similarities between density and volume?
1. Both density and volume are
physical properties of matter
. They are present in the traditional stages of matter, which are solid, liquid, and gas. Both density and volume have a specific formula regarding solids or regular-shaped objects.
What is the amount of mass?
Mass is
a measure of the amount of matter that an object contains
. The mass of an object is made in comparison to the standard mass of 1 kilogram.
