2. (PRO Version) In the equation: MnO2 + HCl => MnCl2 + Cl2 + H2O, if we consume
3.2 liters of 1.332M hydrochloric acid, how many liters of water
will we produce assuming a water density of 1000 grams/liter?
Solution:
-Enter above equation and hit SUBMIT.
-It will balance it.
-Then enter
3.2 in liters column and 1.332 in moles/liter column of HCl.
