Quick breаds аnd biscuits use the thermаl decоmpоsitiоn of sodium bicarbonate as their source of gas for rapid inflation instead of yeast to make the dough rise. The chemical reaction follows: 2 NaHCO3 (s) → Na2CO3 (s) + CO2(g) + H2O (g) What mass (g) of NaHCO3 is required to provide 5.25 L of CO2 gas at 450 K and 1.00 atm? Hint: molar mass of NaHCO3 is 84.01 g/mol
