Considering the definition of percentage by mass, the sample of pure lithium nitrate contains 7.99% lithium by mass.
<h3>Definition of percentage by mass</h3>
The percentage by mass expresses the concentration and indicates the amount of mass of solute present in 100 grams of solution.
In other words, the percentage by mass of a component of the solution is defined as the ratio of the mass of the solute to the mass of the solution, expressed as a percentage.
The percentage by mass is calculated as the mass of the solute divided by the mass of the solution, the result of which is multiplied by 100 to give a percentage. This is:
<h3>This case</h3>
Because percent by mass indicates the ratio of solute to solution based on mass, if the sample has twice the mass of the first sample, the ratio remains constant.
So the percentage by mass is the same.
That is, the sample of pure lithium nitrate contains 7.99% lithium by mass.

Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
A financial goal that I have is to have a well-paying job as I get out of high school so I can afford to go to a University of my choice. This way I won't be in crippling debt and have to take out massive student loans. However, inflation as well as taxes will influence this. Income taxes will force me to have to give up some of my hard-earned money, which will significantly reduce the amount of money I actually make.
I hope this helps! :D If so, will you add it as the brainliest? Thanks! :D
The reason why the Cancer Conference (Tumor Board) can share some PHI with other physicians is that it is a not covered entity.
<h3 /><h3>What is a not covered entity?</h3>
These are entities that are not subject to the Health Insurance Portability and Accountability Act (HIPAA) rules which include those of privacy.
As a result, they can share PHI with other physicians to get better insight on conditions affecting their patients.
