How do you calculate the atomic weight of a metal using its atomic radius and density?

Given the density, you can find the volume per mole of metal by taking dividing the molarity by the density. Using this, you can find the volume of a mole of atoms (this is a different value) by multiplying to the volume per mole of the metal by the packing efficiency. Next, divide the volume of a mole of atoms by the Avagadro's number. Then, using the volume of a sphere, you can find the radius.
Here's a better explanation using formulas:
Volume per mole of metal = Molarity/Density
Volume per mole of atoms = (Volume per mole of metal) x (Packing Efficiency)
Volume of 1 atom = Volume per mole of atoms/6.022 x 1023
Volume of 1 atom = (4/3) x pi x radius3

∙ 16y agoI have just been asked this question on an assignment and found your question is the process of discovering the answer. I found out how to do it and this formula can be used:
density= [(#of atoms per cell) / (volume)] x [(molar mass)/(Avogadro's #)]
only use the Avogadro # if you need the weight in g/mol

∙ 13y agoThe most readily accessible method to determine the atomic weight of an atom is to look it up on the Periodic Table of the elements.
Every element symbol on the Periodic Table has two numbers next to it, both small, one above the other. The smaller number is the Atomic Number, the bigger one, the Atomic Mass, sometimes called the Atomic Weight.

Calculatethe density of Bcc iron at room temperature from the atomic radius of 1.24A and atomic weight of 55.85gmolAvogadro number 6.02310E-23atomic A110E-8cm?
density = 7 897 kg/m^3 = 7.897 g/cm^3
What is the atomic radius of sodium in meters?
Atomic weight of all elements are relative to oxygen atom being taken as 16. The atomic weight of sodium is 6.940. Sodium metal has a density of 0.59. Density is mass per unit volume. Therefore the atomic volume of sodium is 11.763. Assuming atoms and molecules are spheres, the radius is the cube root of 11.763 divided by (pi x 4/3). But, this is relative oxygen, the radius of which in angstrom units has been determined The only purpose of knowing the radius of an atom is to calculate its atomic or molecular volume, which, in the case of gases is very nearly the same by calculation but maybe universally equal in fact. The original determination of the atomic weights of the inert gases was the mass of 22.4 litres of each of them. I, personally, determined the atomic weight of iron accurately to 5 decimal places in the chemistry laboratory of my local university, by chemical means. I could have calculated the atomic volume had that have been required.

How can one easy calculate the kinetic diameter or an equivalent measure of a given molecule?
Firstly, calculate the molecular volume by dividing the product of molecular density and the molecular weight by the Avogadro number. Then take a third root of the volume, the found value is the atomic radius. Then multiply it by 2 to find the diameter.
The weight of the body on the surface of the is 250N. calculate its weight at distance equal to half of radius of the earth below the surface of earth. (radius of earth6400km)?
This is hard to calculate precisely, due to the fact that Earth's density increases towards the center. However, you make a simplified calculation, by assuming a uniform density. Just calculate the ratio of the volume (and therefore, of mass) of a sphere which has half the radius of the Earth, and calculate the gravitational attraction (once again, you only need a ratio, compared to the complete Earth) on that object.
How do you calculate volume if given bulk density?
Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.

How do you calculate the outside diameter of a steel coil based on the weight width and inside diameter?
You're essentially trying to calculate the diameter of a cylinder with a hole in the middle. There are two formulas for volume which you need. Volume= Pi * r2 * h (where Pi=3.142, r = radius of the coil, h = width of the coil) Volume= Weight/Density Since both these formula equal Volume: Weight/Density= Pi * r2 * h Since the weight you have is for a cylinder with a hole in it, you need to calculate the volume of the whole cylinder (without the hole) and subtract the volume of the hole. So for a steel coil Weight/Density = (Pi * rc2 * h)-(Pi * rh2 * h) where rc= the radius of the coil and rh = the radius of the hole (Radius=diameter/2) you're trying to calculate the radius of the coil, so rearrange the formula to get: ((Weight/Density)/Pi*h) + rh2 = rc2 The diameter of the coil = 2 *rc NOTE:- It's important to keep your units of measure consistent throughout the calculation. Density is generally represented by kilograms per cubic metre (kg/m3) - for us metric users ;-) Therefore keep your coil weight in kgs and your radius / width measures in metres.
