Ammonium perchlorate (NH, CIO) is the solid rocket fuel that was used by the U.S. Space Shuttle and is used in the Space Launch System (SLS) of Artemis rocket. It reacts with itself to produce nitrogen gas (N₂), chlorine gas (C1₂), oxygen gas (O₂), water (H₂O), and a great deal of energy. What mass of oxygen gas is produced by the reaction of 3.73 g of ammonium perchlorate? Be sure your answer has the correct number of significant digits. 0 X
