a.
Answer to Problem 47A
The amount of fluorine is
Explanation of Solution
The given chemical reaction is depicted as follows:
When five moles of fluorine react with two moles of ammonia, it yields one mole of tetrafluoro hydrazine and six moles of hydrogen fluoride.
The amount of ammonia is
The molar mass of ammonia is
The molar mass of fluorine is
Therefore, the grams of fluorine can be calculated as follows:
b.
Interpretation: To calculate the amount of ammonia in grams.
Concept Introduction: A mole is
The coefficients are the numbers that are written in front of the chemical formula/symbol in order to balance a chemical reaction. In a balanced chemical equation, the coefficients help in determining the conversion factors between the number of moles for two different substances in a chemical equation.
