Quizplus · Accepted Answer

To find the grams of NaF needed, first calculate the moles of SF₄ using its molar mass (108.07 g/mol). Then, use the stoichiometry of the balanced equation (4 moles of NaF produce 1 mole of SF₄) to find the moles of NaF required. Finally, convert moles of NaF to grams using its molar mass (41.99 g/mol). This calculation results in approximately 754 g of NaF needed.
