Both the feathers and the lead have a mass of 12 g. The trick in the question is that feathers are less dense and have a larger surface area in proportion to their mass, so they would fall a lot slower and be a lot larger than the same mass of lead.
The atomic mass of carbon-12 is defined as 12 atomic mass units (amu). This corresponds to the mass of a single carbon-12 atom relative to 1/12th of the mass of a carbon-12 nucleus.
The mass of 12 protons is approximately equal to 12 atomic mass units.
One atomic mass unit is defined as 1/12 the mass of a carbon-12 atom. This standard was established to provide a reference point for comparing the masses of different atoms. It allows for more precise measurements and comparisons in the field of atomic and nuclear physics.
one mole of carbon-12 contains 6.02 x 1023 grams of carbon-12
Mass of Carbon-12 = 12 amu 5times of mass of Carbon-12 atom = 5 x 12 = 60 amu So atomic mass of element X = 60 amu Rachel- www.examville.com ,tutor
Lead is a non element. Atomic mass of it is 12.
To find the mass of 1.00 x 10^12 lead atoms, you would first determine the molar mass of lead (Pb), which is 207.2 g/mol. Then, divide the total number of atoms by Avogadro's number to get the number of moles, and finally multiply by the molar mass to get the mass. So, the mass of 1.00 x 10^12 lead atoms is approximately 3.14 x 10^-9 grams.

12. The number 12 refers to the atomic mass. More precisely, to the sum of neutrons + protons; but this is usually close to the atomic mass. In the case of carbon-12, it is exact, by definition.
You have to tell us who made it. feather weight

The mass of 12 protons is approximately equal to 12 atomic mass units.
it has at least 12 more nipples than a goat, thats why...
The weight (not mass) is 69.05 pound weight.
One atomic mass unit is defined as 1/12 the mass of a carbon-12 atom. This standard was established to provide a reference point for comparing the masses of different atoms. It allows for more precise measurements and comparisons in the field of atomic and nuclear physics.
The mass of 1 gram of carbon 12 is the same mass as 1 gram of carbon 13.
