The molar mass of HF (hydrofluoric acid) is 20.01 g/mol. Therefore, 3 moles of HF would be equal to 60.03 grams.
First, balance the chemical equation between Na2SiO3 and HF to determine the stoichiometry. Then, use the molar masses of Na2SiO3 and HF to convert the mass of HF to moles. Finally, use the stoichiometry to calculate the mass of Na2SiO3 that can react with 0.740 g of HF.
It will require many pages of a text-book to show the area- formulae for all figures.
