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.

Explanation:
Answer:
TRUE
Explanation:
The trees are the primary producers that produces the food on which the consumers are dependent. This forms the base of the ecological pyramid for both energy as well as biomass.
In any biological condition, it can be observed that during its ecological succession from one trophic level to the next, almost 90% of its total energy is lost, and only 10% of its energy is transferred to the successive trophic level.
Similarly, biomass is also comparatively higher in producers like plants and trees than in any other trophic levels.
Thus, the given statement is True.
