Magnesium metal, Mg (s), reacts with water, H₂O (l), to form magnesium hydroxide and hydrogen gas, H₂ (g). What mass of hydrogen gas can be produced in the reaction of 146.0 g of magnesium with 193.3 g of water? Assume the reaction goes to completion and that it occurs at room temperature and pressure. Molar mass: for the hydrogen atom, H, must use 1.008 g/mol. Thus, for H₂ (g) use 2.016 g/mol Do NOT include units in your answer. If you round during your calculation, be sure to keep at least three (3) decimal places. Report your answer to one (1) decimal place.
