Why the theoretical density is greater than the actual density of nickel?

When you consider the theoretical density of a material, you consider a material where every atomic position is filled with an atom of that material in a perfect lattice arrangement with no errors. For example, if you consider Nickel, each of the atomic positions are filled with a Nickel atom. So if this were to occur over 1g/cm^3, you have a theoretically dense Nickel. However, in this universe this is virtually impossible, as we know it anyway! :) Real world materials, no matter how brilliant your processing parameters always contain some impurities (other atoms besides Nickel), flaws, missing atoms (called a vacancy), porosity, etc... All of these things bring the density of the Nickel away form the theoretical density and you end up with the "real world" density of the material. This is a basic explanation, but I hope it gives some information and helps in kicking off some research on the net. Materials Scientist, PhD.


What is the volume of 24 mmol of ethyl iodide and the theoretical yield of p-ethoxynitrobenzene?

The volume of 24 mmol of ethyl iodide would depend on its density, which is about 2.29 g/cm³. To calculate the volume, you would need to convert 24 mmol to grams using the molar mass of ethyl iodide (155.99 g/mol) and then divide by the density. The theoretical yield of p-ethoxynitrobenzene would depend on the reaction conditions and stoichiometry of the reaction involving ethyl iodide, but you would use the molar ratio of ethyl iodide to p-ethoxynitrobenzene to calculate the theoretical yield.


Would the percent yield be different if the actual yield and theoretical yield were in units of moles?

No, the percent yield would not be affected by the units of the actual and theoretical yield as long as they are consistent. Percent yield is calculated as (actual yield / theoretical yield) x 100%, where the units cancel out in the division.


What is the height equivalent to a theoretical plate in chromatography?

The height equivalent to a theoretical plate in chromatography is a measure of the efficiency of the column packing material. It represents the distance that a solute must travel in the column to achieve the same degree of separation as it would on a single theoretical plate.


Why could an actual yield be more than a theoretical yield?

An actual yield can be more than a theoretical yield due to incomplete reaction conversion, impurities in reactants, or unexpected side reactions. These factors can result in more product being formed than predicted by theoretical calculations.

How do theoretical density different to density?

Theoretical density refers to the calculated density of a material based on its molecular structure and atomic weights. It is a theoretical prediction. Density, on the other hand, is the measurement of the mass of a material per unit volume. It is typically determined experimentally.


What is the factor on the density theoritical?

It is theoretical because cell density cannot be forced to reach maximum density.


Does hassium have density?

All materials have a density. It is impossible to measure the hassium density; a theoretical estimate is 40,7 g/cm3.


What is underlying distribution?

Underlying distribution is a concept that describes the density for the value of the measurement. It is a theoretical concept.

What is infinite density?

Infinite density is a theoretical concept that describes a point of extreme compactness where the mass of an object is compressed into an infinitely small volume. It is often associated with black holes, where gravity is so strong that it causes matter to collapse into a singularity with infinite density at the center.


How do you find the probability density function?

The probability density function of a random variable can be either chosen from a group of widely used probability density functions (e.g.: normal, uniform, exponential), based on theoretical arguments, or estimated from the data (if you are observing data generated by a specific density function). More material on density functions can be found by following the links below.


What is the density of francium at STP?

The density of francium at standard temperature and pressure (STP) is approximately 1.87 grams per cubic centimeter. Francium is a highly radioactive element and is rare in nature, so its properties are mainly theoretical.


Can density determine if an object is hollow?

If we know the material that makes up the object, we will also know the density of the material. By measuring the volume and mass of the object, it is possible to find out if it is solid or hollow. This will only work if we know the material and we know the density of the material.
