|
To change from moles of a given substance, to moles of the substance sought, one uses the ____
|
|
ratio of the molar masses of the two substances.
|
|
|
balanced equation coefficients for the substances.
|
|
|
subscripts in the formulas for the substances.
|
|
|
all the above
|
Explanation:
Detailed explanation-1: -The mass of the given substance is converted into moles by use of the molar mass of that substance from the periodic table. Then, the moles of the given substance are converted into moles of the unknown by using the mole ratio from the balanced chemical equation.
Detailed explanation-2: -This is the comparison between the coefficients in front of the chemical formulas. If a formula lacks a coefficient, it is the same as saying there is 1 mole of that species. Mole ratios are used to predict how much product a reaction forms or to determine how much reactant is needed to make a set amount of product.
