Hydrofluoric acid, HF(aq), cannot be stored in glass bottles because compounds called silicates in the glass are attacked by the HF(aq). Sodium silicate (Na2SiO3), for example, reacts as shown below.
Na2SiO3(s) + 8 HF(aq) → H2SiF6(aq) + 2 NaF(aq) + 3 H2O(l)
(a) How many moles of HF are needed to react with 0.220 mol of Na2SiO3?
(b) How many grams of NaF form when 0.430 mol of HF react with excess Na2SiO3?
(c) How many grams of Na2SiO3 can react with 0.813 g of HF?
Could you show me how you solved it because i have a lot more of these questions on my homework
