The density of anything can be found using m/v=d. where m is mass, v is volume, and d is density. therefore you find the volume of the coin (whether it be penny, nickel, dime, quarter, or peso) and then mass the coin on a balance and work the problem out.
There are many different masses of many different coins such as 5.7 grams for a quarter. This is because there are many different size coins in the world.
The SI unto of mass is the kilogram, a coin would be measured in one of the subdivisions of the kilogramme = usually grammes.
The exact mass of a Canadian penny is 2.35 g

you drop the coin into water and find volume then weigh it to find mass if the volume is greater than mass it will float.
You would use grams, or milligrams for more precision.
The standard mass (weight) of coins is the gram. (1 gram is equal to one thousandth of a kilogram: 0.001).
I suggest you use grams.
Grams - to 2 decimal places.
2.35
21 grams
The mass of any coin is typically measured in grams; the capacity or volume would be measured in millilitres.
grams or meters weight or length
Units of measurement provide a standard to measure mass, length etc.So, it is useful.
The base unit of mass is the kilogram.
Mass is measured in kilograms.
Kilograms.
tons
Kilograms.
Meters for height Kilograms for mass.
A mass balance.
In layman's terms "mass" means weight. The measurement is expressed in grams, and to measure mass, a scale is used.
Usually you would weigh it, on a device that is calibrated to show mass.
They would use the measurement milligrams.
A millinewton. NOT a gram, which a measure of mass, not of weight.
kilograms
No Weight is a measurement of force... mass is not.
