Question

Based upon the following balanced equation:

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

How many grams of manganese(IV) oxide (MnO2) should be added to an excess of hydrogen chloride gas to obtain 380 mL of chlorine gas at 25oC and 752 mmHg?

Assume you can ignore the vapor pressure of water.

Your answer should have 3 significant figures.  Do not include the units in your answer.
