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

To calculate the density of BCC iron, you can use the formula: density = (atomic weight * Avogadro number) / (atomic volume). First, convert the atomic radius to cm (1.24A = 1.24 * 10^-8 cm). Then, calculate the atomic volume using the formula for BCC structure. Finally, plug in the values to find the density.
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.
Why is silver more dense than gold?
Silver is less dense than gold! Pure silver has a density of 10.49 g·cm−3 whereas gold has density of 19.30 g·cm−3 The principal reason why gold is more dense is that the atoms are much heavier. Silver has an atomic weight of 107.9 , gold has an atomic weight of 196.97.
What is the formula to calculate teflon round bar weight?
The formula to calculate the weight of a Teflon round bar is weight = volume x density. First, calculate the volume of the round bar using the formula for the volume of a cylinder: volume = π x (radius)^2 x length. Next, multiply the volume by the density of Teflon to find the weight of the round bar.
What is the atomicity of a gas if it's vapor density is 28 and atomic weight is 14?
The atomicity of a gas can be determined by comparing its vapor density to its atomic weight. In this case, if the vapor density is 28 and the atomic weight is 14, the atomicity of the gas is 2. This means that each molecule of the gas consists of 2 atoms.

How do you calculate weight of HDPE pipe?
To calculate the weight of an HDPE pipe, you can use the formula: Weight = Volume × Density. First, calculate the volume of the pipe using the formula for the volume of a cylinder (πr²h, where r is the radius and h is the height), and then multiply it by the density of HDPE to get the weight. Density of HDPE can range from 0.93 to 0.97 g/cm³ depending on the grade.
How do you calculate weight of frustum?
To calculate the weight of a frustum, first determine its volume using the formula: ( V = \frac{1}{3} \pi h (R^2 + r^2 + Rr) ), where ( R ) is the radius of the larger base, ( r ) is the radius of the smaller base, and ( h ) is the height. Once you have the volume, multiply it by the material's density (( \text{Weight} = \text{Volume} \times \text{Density} )) to find the weight of the frustum.

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.
How do you Calculate the weight of a Cone?
You can calculate the weight of a cone by using the formula: weight = volume x density x gravitational acceleration.
