What unit of measurement would be used to measure the mass of a feather
Yes a feather is lighter than water. Water can be gallons. A feather however is no pounds. If you have a scale at home than fill up a cup of water than get a feather, from like a scarf a pillow etc. And put the water on first, then write down the number. Then put the feather on the scale and write down that number then compare.
If you are trying to measure concentration of salt in water you would be measuring molarity which is moles / liter. Moles are equal to grams of salt / the MW of salt (and if you mean NaCl then the MW is 58.44 g/mol). Density is a ratio of mass to volume (mass / volume or kg/m^3)
Density is a measure of how tightly matter is packed. It is calculated by dividing the mass of an object by its volume. The higher the density, the more mass is packed into a given volume.
Even though feathers are light and rocks are heavy, when 100 kilograms of each are placed on a scale, they will exert the same downward force due to gravity. Weight is a measure of the force of gravity on an object, so in this case, both the feathers and rocks will weigh the same.
In 1971, astronaut David Scott dropped a hammer and a feather on the moon during the Apollo 15 mission to demonstrate Galileo's theory that objects of different mass would fall at the same rate in a vacuum. This experiment showed that in the absence of air resistance, the hammer and feather landed at the same time, supporting Galileo's prediction.
Depending on the size of the feather - grams or milligrams.
I suggest the millinewton. However, please note that people commonly confuse weight and mass; if it is actually the mass you want to measure, then use the gram.
Since kilograms are the unit we use to measure mass, the answer is no: both have 1kg. of mass. :D
A balance or a scale is typically used to measure the mass of a feather. Feathers are very light, so a precise and sensitive instrument is required to accurately measure their mass.
The best way to measure the mass of a feather is to use a precision digital scale. First, ensure the scale is calibrated and set to zero before placing the feather on it to obtain an accurate measurement. For more precision, especially with very light feathers, consider using a sensitive balance that can measure in milligrams. Additionally, ensure that the feather is clean and dry to avoid any weight from moisture or debris.
grams because a feather would not be measured in kilograms
The appropriate unit to measure weight is the newton. Now, if it is really the mass you wanted, you could use kilogram or gram.
Mass is a measure of the amount of matter in an object. The more mass, the more matter. The Brooklyn Bridge is quite massive - has a lot of mass, whilst a feather has slight mass.
A stone is heavier than a feather because of its higher density. Density is a measure of how much mass is contained in a given volume, and stones typically have a much higher density than feathers. This means that for the same volume of material, a stone will have more mass and therefore weigh more than a feather.
That depends what you want to measure: its length, width, weight, mass, color, volume, surface area, air resistance, etc.
You Use Atomic Mass Number
Millinewton can be the best unit for measuring the weight of feather.
