Answer 1

$\qquad \qquad \bf \huge\star \: \: \large{ \underline{Answer} } \huge \: \: \star$

B. How much of the reactants are needed and how much product will be made.

Chemists use mole in calculations to calculate the amount of product that will be formed when certain known amount of reactants are used at the end of reaction.

Answer 2

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.

What are moles?

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.
