Gas Laws Stoichiometry A student needs to prepare some CO2 and intends to use to following reaction in which CACO3 is heated strongly. They are wondering how large a container should be used if 1.25 g of CaCO, is used. The pressure is 744 torr at 25°C. What size of flask should they use in liters? 1 CaCO3 -> 1 CO2 + 1 Сао In one lab, the gas collecting apparatus used a gas bulb with a volume of 256 ml. How many grams of NazCO; would need be used to prepare enough CO2 to fill this bulb when the pressure is 738 torr at 23°C? 1 Na,CO, 2 HCI > 2 NaCl + 1 CO + 1 HO
