The answer is 7,5g.
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.
The HF band is considered to be 3 Mhz to 30 Mhz.
3 pounds equals to 1360.77711 grams
The gram molecular mass of HF is 20.01. Therefore, 0.589 mole has a mass of 11.79 grams and is sufficient to form 0.589 mole of sodium fluoride* when sodium is present in excess. The gram molecular mass of sodium fluoride is 41.99, so that 0.589 grams of it has a mass of 24.7 grams, to the justified number of significant digits. __________________________ The formula unit of both hydrogen and sodium fluorides contains a single fluorine atom.
