Aqueous hydrochloric acid reacts with magnesium to produce hydrogen gas according to the balanced equation below. 2 HCl(aq) + Mg(s) → MgCl2(aq) + H2(g)
If 250.0 mL of 3.00 M HCl is combined with 9.92 g Mg,what volume of hydrogen gas can be produced? Assume the temperature and pressure of the gas are 25 °C and 0.988 atm,respectively.(R = 0.08206 L⋅atm/mol⋅K)
A) 4.60 L
B) 5.05 L
C) 9.28 L
D) 10.1 L
