The gram is the basic unit for mass
white dwarf
Low and medium sized stars will end up as white dwarfs.
A mass. A medium sized dog might have a mass of 15 kg.
The Sun is a medium mass star in main sequence.
potassium dichromate- K2Cr2O7 12.5 grams K2Cr2O7 *(1 mol K2Cr2O7/294 grams K2Cr2O7)= .0425 mols K2Cr2O7 There's two mols of K (potassium) for every 1 mol of K2Cr2O7 (Potassium Dichromate) so you multiply the K2Cr2O7 by two to get mols of K .0425 mols K2Cr2O7*(2 mols K/1 mol K2Cr2O7)=.085 mols K Multiply by the molar mass of K to get grams .85 mols K*(39 grams/1 mol K)= 3.32 grams potassium
The chemical formula of potassium dichromate is K2Cr2O7; and the molecular mass is 294,185.
The number of potassium atoms is 2,04.10e21.
The three stages in the development of a new mass medium are emergence, entrepreneurial, and mass medium. In the emergence stage, a new technology or platform is created. In the entrepreneurial stage, innovators experiment with the new medium to determine its potential. In the mass medium stage, the medium gains widespread adoption and becomes a standard part of communication.
Percent by (basic) mass is easy... K2 = 39 x 2 = 78 Cr2 = 52 x 2 = 104 O7 = 16 x 7 = 112 % by mass = 112/(78+104+112) = 56/142 = 29.9465% If you're looking for a more complex/precise derivative that includes the probabalistic mass of the electrons, etc. then it becomes much more complicated. -D

no the sun is a medium mass star.
Low and medium sized stars will end up as white dwarfs.
Most types of waves are considered to have no mass. eg. Light has no mass, its really just a vibration of electromagnetic energy. If you have no mass, then their is no force to act upon the medium.
no the sun is a medium mass star.
What actually happens to the types of stars is that the low mass will turn into a white dwarf and the medium mass will turn into a black dwarf and reproduce a nebula
