Everything has mass and volume, and therefore density. However, there are interesting facts about Iron that most don't know about. If you simplify and treat each atom as a cube, (a) what is the average volume (in cubic meters) required for each iron atom and (b) what is the distance (in meters) between the centers of adjacent atoms? So it is expected that the smallest piece of matter, like an atom of Iron has it too. Problem 1 Easy Difficulty. meter. Click hereto get an answer to your question ️ Iron has a density of 7.87 g/cm^3 , and the mass of an iron atom is 9.27 × 10^-26 kg . About Iron; 1 cubic meter of Iron weighs 7 873 kilograms [kg] 1 cubic foot of Iron weighs 491.49533 pounds [lbs] Iron weighs 7.873 gram per cubic centimeter or 7 873 kilogram per cubic meter, i.e. Calculate the recoil kinetic energy of the atom. volume of iron atom = mass/density = 1.177 x 10-29 cu. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100. If the atoms are spherical and tightly packed,What is the distance between the centres of adjacent atoms? if iron atom is a cube then side of the cube is cube root of volume or 2.274 x 10-10 m. the distance betwen two iron atoms is same as side of cube meter. How to Convert Atomic Mass Unit to Kilogram. In the case of Iron , density is 7.86 g/cm³. Mass of an iron atom = {eq}9.3 \times 10^{ -26 } \ kg {/eq} Kinetic energy of the atom. 1 u = 1.6605402E-27 kg 1 kg = 6.0221366516752E+26 u. Iron Bromide (FeBr 3) Iron Oxide (Fe 2 O 3) Iron Sulphide (FeS) Interesting facts: Iron is present in every cell in the body, but of it is found in the hemoglobin or myoglobin. A free atom of iron emits K α X-rays of energy 6.4 keV. The atomic masses of these atoms are 4.00 u, 55.9 u, and 207 u, respectively. Without enough iron in your body, you can become anemic. 10 25 of them are valence.. Mass of all electrons is about 0.26 g, i.e. electrons contribute very slightly to the mass … Common Uses: Cast iron for ovens and engine cylinder blocks Example: convert 15 u to kg: 15 u = 15 × 1.6605402E-27 kg = 2.4908103E-26 kg The kinetic energy of the atom depends upon the momentum of the particle. Note: Learn more about the density here. Mass of an iron atom = 9.3 x 10 -26 kg. Give your answers in kilograms. Molar mass of Fe = 55.845 g/mol. density of iron 7870 kg per cu. It is a very important dietary requirement. ›› Iron molecular weight. An iron nucleus has a radius of 5.4x10^-15 and a mass of 9.3x10^-26 what is its mass per unit volume in kg/m^3 Homework Equations Area of a sphere = 4/3(pi)r^3 Density= M/V The Attempt at a Solution i basically plugged everything into the equations so calculated the volume and put it into the density equation but my answer is far to high i think mass of iron atom=9.27 × 10-26 kg. Calculate the mass of an atom of (a) helium, (b) iron, and (c) lead. Homework Statement Iron has a mass of 7.87 g per cubic centimeter of volume, and the mass of an iron atom is 9.27 * 10^-26 kg. But what is the density of an atom of Fe?
