When sulfuric acid reacts with sodium bicarbonate, carbon dioxide gas is released. If 2.0 L of CO2 gas is collected at standard temperature and pressure, how many grams of sodium bicarbonate we consumed? (use ideal gas law - R = 0.0821 l*atm/mol*k) H2So4 (aq) + 2NaHCO3 (aq) -> Na2SO4 (aq) + 2H2O (I) + 2CO3 (g) a) 7.5 g b) 8.7 g c) 3.9 g d) 4.7 g
