The hypothesis would be that more green bugs would be found than bright red bugs because the green bugs are more camouflaged asunder the green plants than the bright red bugs.
The moles are used to determine the atoms and molecules in a substance. It is used by chemists to determine the amount of reactants needed and products produced. Thus, option B is correct.
<h3>What are moles?</h3>
A mole is said to be defined as the estimation of the small entities like the atoms as that of the Avagadro's number 6.022 × 10²³. It defines the number of particles contained in a substance.
The moles of the substances are determined by the mass of the substance and its molar mass. The moles are given as,
Moles = mass ÷ molar mass
The moles give the estimation of the amount of the reactants needed to produce the products in a chemical reaction.
Therefore, option B. the moles tell the amount of the reactants required to produce the product.

B) When describing very dilute solutions.
Explanation:
The most appropriate time to use ppm is when describing dilute concentrations of solutes in solutions. It is used mostly to determine trace amount of elements in water and soils.
- The part per million ppm is the amount of miligram of a solute in a liter of solution.
- It is similar to percentage.
- Minute and trace concentrations are very difficult to work with.
- Using parts per million, they become better appreciated and easy to use.
