If you need a high precision answer, look in "Kaye and Labey" or Google it.
If an approximation will do, it is ~ 6.02 x 1023. Good to 1 part in 500.
(no units - this is a pure number)
Avogadro's number is a constant (6.022 x 10^23) that represents the number of particles (atoms, molecules, ions, etc.) in one mole of a substance. It is used to convert between the mass of a substance and the number of particles it contains.
LEDs (Light Emitting Diodes) are used in determining the Planck constant because they emit light at specific frequencies when electrical current is applied. By measuring the voltage needed to produce light of a known frequency, the relationship between energy and frequency can be studied, allowing for the accurate determination of the Planck constant.
Determining the cell constant is necessary because it allows for accurate calibration of the conductivity meter. The cell constant is used to convert the measured electrical conductivity into a value that corresponds to the actual concentration of ions in the solution being tested. Failure to determine the cell constant correctly can lead to inaccurate conductivity readings and incorrect data analysis.
Equal amounts of all gases have the same volume at the same conditions.
By finding a constant, continuous change in the coordinates of stars every year.
6.02*10^23atoms (avogadros constant)
There is 1 mole of atoms in 6.022 x 10^23 atoms of any element.
determine if the momentum of an object moving in a circular path at constant speed is constant.
As far as I can determine, it is the largest magnitude constant.
No.
Its avogadros number
A mole.
determine if the momentum of an object moving in a circular path at constant speed is constant.
you have to beat someone up
You can determine if a rate of change is constant, by taking the instantaneous rate of change at multiple points - if they are all equal to each other, it can be assumed that the rate of change is constant. Alternatively, you can differentiate the function (if there is an associated function) - if this comes to a constant i.e. a number, then the rate of change is constant.
V=kn
The rate constant is the reaction rate divided by the concentration terms.
