Question

How many grams of HCl reacts with 8.7 gram of MnO2?
MnO2 + 4HCL
MnCl2 + 2H20
(atomic mass of Mn = 55,0 = 16, Cl= 35.5)
a 1.46 g b) 14.6 g c) 7.3 g d) 3.65 g​

Answer 1

Answer:

First you balance the equation

Then,

Number of moles equals reacting mass over molar mass

Answer 2

Answer:

b) 14.6 g

Explanation:

First you balance the equation.

Then, Number of moles equals reacting mass over molar mass.

If you complete it, you will get the answer as:

14.6 grams of HCl reacts with 8.7 gram of MnO2.
