But what is the density of an atom of Fe? 10 25 of them are valence.. Mass of all electrons is about 0.26 g, i.e. If the atoms are spherical and tightly packed,What is the distance between the centres of adjacent atoms? 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. Give your answers in kilograms. So it is expected that the smallest piece of matter, like an atom of Iron has it too. However, there are interesting facts about Iron that most don't know about. 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. meter. Calculate the mass of an atom of (a) helium, (b) iron, and (c) lead. Problem 1 Easy Difficulty. In the case of Iron , density is 7.86 g/cm³. 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. The atomic masses of these atoms are 4.00 u, 55.9 u, and 207 u, respectively. volume of iron atom = mass/density = 1.177 x 10-29 cu. The kinetic energy of the atom depends upon the momentum of the particle. 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. 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? Molar mass of Fe = 55.845 g/mol. mass of iron atom=9.27 × 10-26 kg. meter. 1 u = 1.6605402E-27 kg 1 kg = 6.0221366516752E+26 u. Mass of an iron atom = {eq}9.3 \times 10^{ -26 } \ kg {/eq} Kinetic energy of the atom. density of iron 7870 kg per cu. ›› Iron molecular weight. 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 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 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 . Calculate the recoil kinetic energy of the atom. Mass of an iron atom = 9.3 x 10 -26 kg. electrons contribute very slightly to the mass … How to Convert Atomic Mass Unit to Kilogram. Example: convert 15 u to kg: 15 u = 15 × 1.6605402E-27 kg = 2.4908103E-26 kg Without enough iron in your body, you can become anemic. Everything has mass and volume, and therefore density. Common Uses: Cast iron for ovens and engine cylinder blocks A free atom of iron emits K α X-rays of energy 6.4 keV. It is a very important dietary requirement.
