A sample Mg metal reacts with excess aqueous hydrochloric acid to produce 257.3 mL of dry hydrogen at a pressure of 1.00 atm and a temperature of 27.1 °C. How many moles of hydrogen gas are produced? (R = 0.08206 Lam :) mol-K Answer: Theoretically, if 0.192 grams of Mg metal was reacted with excess aqueous hydrochloric acid how many moles of hydrogen gas should be produced? (R = 0.08206 and the molar mass of Mg = 24.3050 g/mol) L-atm mol-K Answer: I Choose...
