A yoctogram is a unit of mass equal to 10-24 grams.
yoctogram
The yoctogram which is 0.000 000 000 000 000 000 000 001 grams.
At present, that would be the yoctogram, simply because "yocto-" is the smallest submultiplier. You could, of course, compound the prefixes, as "centimicroyoctogram," but the real value of such units is dubious; almost anything you needed to weigh would be more than a yoctogram.
I have been studying this in science class. The answer to your question has more than one. If the atomic mass unit is 1 gram of hydrogen, the number of atoms would be about 15 to 22. If there is more than 1 gram of hydrogen, the answer will vary.
That is the element's mean atomic mass. It's the average atomic mass of the element as found in nature, taking into account how abundant each isotope of the element is in nature. The number of protons in an atom determines what element it is, but not all atoms of many elements have the same number of neutrons in nature. The total number of protons and neutrons determines which isotope of the element it is, and almost all of an atom's mass is in its protons and neutrons. Atomic mass is measured in atomic mass units (amu). One atomic mass unit is equal to one twelfth of the mass of a carbon-12 atom in its ground state. That is approximately 1.660539 yoctograms (a yoctogram is a trillionth of a trillionth of a gram).
Yes. Grams use the same standard unit conventions as meters, bytes, liters, and anything else that uses the Greek naming conventions for unit sizes. So the next units smaller than milligrams would be: 1 microgram = 0.000 001 grams 1 nanogram = 0.000 000 001 grams 1 picogram = 0.000 000 000 001 grams 1 femtogram = 0.000 000 000 000 001 grams 1 attogram = 0.000 000 000 000 000 001 grams 1 zeptogram = 0.000 000 000 000 000 000 001 grams 1 yoctogram = 0.000 000 000 000 000 000 000 001 grams
Oh, absolutely! Just like how we have different sizes of brushes for painting happy little trees, in the world of measurements, there are even tinier units than a yoctometer. You see, there's a zeptometer, which is even smaller and allows us to appreciate the incredible detail and beauty in the tiniest parts of our world. Just imagine the possibilities when we explore these small wonders with a gentle touch and a kind heart.
This depends what you are measuring. The metric system uses prefixes to change the size of units. Litres can have the prefix milli. Millilitres are a thousandth of a litre. Similarly, millimetres are a thousandth of a metre. Other prefixes are: micro = 1/1 000 000; 10-6 nano = 10-9 pico = 10-12 femto = 10-15
