What does density measure?
Density is a measure of mass per unit of volume. The higher an object's density, the higher its mass per volume. The average density of an object equals its total mass divided by its total volume. A denser object (such as iron) will have less volume than an equal mass of some less dense substance (such as water). The SI unit of density is the kilogram per cubic metre (kg/m3)
The quantity of matter in unit volume?
density
What metric unit would you use to measure the mass of a set of encyclopaedias?
You would use grams (g) or kilograms (kg) to measure the mass of a set of encyclopaedias.
What is a unit of measure concept?
A unit of measure is a standard quantity used to express and compare physical quantities, such as length, mass, volume, or time. It provides a consistent framework for measurement, allowing for clear communication and understanding of values. Common examples include meters for length, kilograms for mass, and liters for volume. Units can be part of different systems, such as the metric system or imperial system, each with its own set of standards.
How could you measure the dry mass of human?
To measure the density of anything, one must divide its mass by its volume. Finding the mass of a human is as easy as stepping on a set of scales, but finding the volume is a bit more tricky. The simplest way is to completely immerse the person in a tank of water, and measure how much the water level rises. This will let you calculate how much water was displaced--that amount is the person's volume. For example, if a person weighs 75kg, and displaces 65 liters of water, they'd have a density of about 1.15 (75/65= ~1.15) If you're using pounds and gallons instead, you'll need to divide the result by 8, since a gallon of water weighs 8 lbs. So if a 165 lb. person displaces 18 gallons of water, they'd have a density of about 1.145 (165/18=~9.16, 9.16/8=~1.145)

Why is mass and weight necessary to find density?
the definition of density is the amount of mass contained in a set volumeto find density one must know mass and volume the equation is as follows: density= mass/volume hence, weight is not necessary to find density
What is a way to say density?
Density is defined as a substance's mass per unit of volume (d=m/v). Another way to say this is how much mass is contained in a set quantity of three dimensional space.
How many ml are in 115 grams of sugar?
ml is a measure of Volume, grams is a measure of weight/mass. The two can not be equated except via the density of the substance being measured. Density = Mass/Volume It is easier to use a measuring jug for liquids and a set of scales for dry stuff.
The quantity of matter in unit volume?
density
Unable to afford an entire set of encyclopedias joey bought only what volume?
Volume A, since it contained the entire 'alphabet'.
What are the characteristic of a liquid?
the answer to that question is..................... oh yea! it has a fixed mass and volume BUT NO SET SHAPE
How can you obtain an objects volume if you know it's density and mass?
Density equals mass over volume. Set up the equation and solve for volume.
How do you calculate mass when density is not known?
you can't unless you have a set of weighing scales mass = density * volume density is needed to work out mass if you have volume if you worked out the mass then you could divide it by volume to get density
What do you use to measure the density of a liquid?
density is mass / volume. pour the water into a measuring clyinder, weigh it on scales then minus the weight of the empty clyinder. Divide the mass by the volume and you'll get the density.
What metric unit would you use to measure the mass of a set of encyclopaedias?
You would use grams (g) or kilograms (kg) to measure the mass of a set of encyclopaedias.
How do you calculate volume when given density and mass?
V = M/D, where V is the volume, M is the mass, and D is the density. Density is mass per unit volume. Be certain to use a consistent set of units. The common units for density are kg/m3 and g/cm3. Hello I'm Bob
