| Calculate how many volumes of chlorine can be obtained by reacting 43.5 g of manganese oxide with concentrated hydrochloric acid.
Let’s compose the equation of the process:
MnO2 + 4HCl (conc.) = MnCl2 + Cl2 + 2H2O – OBP, chlorine is evolved;
Calculations by formulas:
M (MnO2) = 86.9 g / mol;
M (Cl2) = 71 g / mol.
Determine the amount of the original substance:
Y (MnO2) = m / M = 43.5 / 86.9 = 0.5 mol;
Y (Cl2) = 0.5 mol since the amount of substances is 1 mol.
Find the volume of the product:
V (Cl2) = 0.5 * 22.4 = 11.2 L
Answer: Chlorine was obtained with a volume of 11.2 liters.
