Answer: 8.702g of HCl
Explanation:
Using the details from the equation;
4HCl(aq) + MnO2(s) → 2H2O(l) + MnCl2(aq) + Cl2(g)
The molecular mass of HCl is; 4 (1 + 35.5) = 146g
The molecular mass of MnO2 is; (54.9 + 32) = 86.9g
From the equation it means;
86.9g of MnO2 reacts with 146g of HCl
if 1 g of MnO2 reacts with 146 ÷ 86.9 of HCl
∴ 5.18g of MnO2 will react with; 146 ÷ 86.9 x 5.18 = 8.702g of HCl
Note: Approximations were made during the determination of the molecular masses.
