Question

2.4 g of pure Mg (at. mass = 24) is dropped in 100 mL of 1 M HCl. Which of the following statement is wrong?, 1.12 L of hydrogen is produced at S.T.P., 0.05 mol of magnesium is left behind, HCl is the limiting reagent, 0.005 mol of magnesium is left behind

M g 2.4 g 0.1 m o l - 0.05 0.05 m o l + 2 H C l ( 1 M , 100 m l ) 0.1 m o l → M g C l 2 + H 2 HCl is a limiting reagent 0.1 mol HCl give 0.1 2 mol H 2 or 1.12 lit H 2 at STP 0.05 mol Mg left So option D is wrong.
