A sample of pure lithium nitrate contains 7. 99% lithium by mass. What is the % lithium by mass in a sample of pure lithium nitr

Shalnov [3]

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:

$percentage by mass=\frac{mass of solute}{mass of solution}x100$

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.

netineya [11]

The species of butterfly that is shown is; Papilio polyxenes.

<h3>What are the species of butterflies?</h3>

Butterflies usually are identified by the colors and patterns shown on their wings. However, for us to identify an organism using a dichotomous key, we must compare the traits of the organism to the first pair of descriptive statements on the key as follows;

1) A swallowtail butterfly is either classified as Papilio glaucus ( where the wings are mainly yellow) or Papilio polyxenes(where the wings are mainly black)

Now, the image of the butterfly given shows that the wings are mainly black, and as a result, we will say that the butterfly specie is called Papilio Polyxenes.
