Yes. Unit of measure is kilogram.
9.81*mass = Newtons of forcethe mass is in kilograms
You don't, 1000 grams is 1 kilogram Divide grams by 1,000 and you have the same mass expressed in kilograms.
Depending how you interpret "quantity of matter", that can refer either to the mass (expressed in kilograms), or the number of moles.
Density is mass per unit volume. It is calculated by dividing the mass of an object by its volume. It is expressed in some unit of mass divided by volume; for example, the SI unit would be kilograms per cubic meter.
That can be expressed by the density, which has units of mass divided by volume - for example, kilograms per cubic meter.
Mass is.
Mass
Mass is not expressed in kilometers (km). That is a measure of distance. Mass is expressed in units of kilograms (kg)
mass
Yes.
9.81*mass = Newtons of forcethe mass is in kilograms
Expressed in kilograms, its mass is(0.003) x (its density)
This is mass of salt expressed in grams, kilograms, tonnes, etc.
Saturn's mass in kilograms is expressed as: 5.686 x 10^26 kg
Planets don't "weigh"; they have a mass. Mass is that which is expressed in kilograms (or pounds, or tonnes).The seventh planet from the Sun is Uranus; its mass is 8.68e25 kilograms, or about 14.5 times the mass of Earth.
Density = mass / volumeIn SI units: mass is expressed in kilograms volume is expressed in cubic meters Therefore, density is expressed in kilograms /cubic meters. (In practice, the unit kilogram/liter, which is equivalent to gram / cubic centimeter, is often still used.)
You don't, 1000 grams is 1 kilogram Divide grams by 1,000 and you have the same mass expressed in kilograms.
