Hello, I'm posting the first chemistry task: ) [martural range] if it is not solved, I will solve it on YT.
As a result of the action of concentrated sulfuric acid at elevated temperature on a sample containing a mixture of sodium formate and sodium carbonate, the following chemical reactions occur: HCOONa+H2SO4 → NaHSO4+CO+H2O Na2CO3+H2SO4 → Na2SO4+CO2+H2O Calculate the mass of sodium carbonate in Na2CO3 and HCOONa sample, knowing that the action of concentrated sulfuric acid (VI) on this sample led to the separation of a gas mixture containing CO and CO2 with a total volume of 23.97 dm^3 (Normal conditions), whose density relative to argon was 0.78.
