Q. 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?

NTA AbhyasNTA Abhyas 2022 Report Error

A

1.12 L of hydrogen is produced at S.T.P.

B

0.05 mol of magnesium is left behind

C

HCl is the limiting reagent

D

0.005 mol of magnesium is left behind

Solution:

HCl is a limiting reagent
0.1 mol HCl give mol or 1.12 lit at STP
0.05 mol Mg left
So option D is wrong.
