Question

chlorine can be prepared in the laboratory by the reaction of manganese dioxide with hydrochloric acid, HCl (aq), as described by the chemical equation

MnO₂(s) + 4 HCl (aq) -> MnCl₂(aq) + 2 H₂O (l) + Cl₂ (g)

How much MnO₂(s) should be added to excess HCl (aq) to abtain 145 mL Cl₂ (g) at 25 degrees celsius and 735 Torr?

Mass of MnO₂= ? g

Expert Solution

Step 1

Given:

Volume = 145 mL = 0.145 L.

Temperature = 25 ^oC = 298 K

Pressure = 735 torr = 0.9671 atm.

Step 2
