Answer: B or C
Explanation: The question does not include the variable or steps Brian is using so either one could be correct. It has to be the one that he is controlling though. This is because a control group is used to rule out any alternate explanations. Therefore the answer should be the one that he is trying to test out.
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.
