Final answer:
To calculate the amount of CH4N4O2 needed to produce 1500.0 liters of gas at STP, use stoichiometry and Avogadro's Law to convert liters of gas to moles of CH4N4O2 and then to grams.
Step-by-step explanation:
To calculate the amount of CH4N4O2 needed to produce 1500.0 liters of gas at standard temperature and pressure (STP), we need to use stoichiometry. First, we need to obtain the balanced chemical equation for the reaction. Assuming the reaction is CH4N4O2 → x gas, we calculate the molar volume of gas at STP using Avogadro's Law and convert it to liters. Then, we use the molar ratio between CH4N4O2 and the unknown gas to calculate the number of moles of CH4N4O2 required. Finally, we convert the moles of CH4N4O2 to grams using the molar mass of CH4N4O2.
