The answer would be letter A
The initial concentration was 8.45M
Step 1: Given data
Initial concentration (C₁): ?
Initial volume (V₁): 635 mL = 0.845 L
Final concentration (C₂): 6.00 M
Final volume (V₂): 1.19 L
Step 2: Calculate the initial concentration
We have a concentrated NaCl solution and we want to prepare a diluted one. We will use the dilution rule.
C₁ × V₁ = C₂ × V₂
C₁ = C₂ × V₂ / V₁
C₁ = 6.00 M × 1.19 L / 0.845 L
C₁ = 8.45 M
Thus, The initial concentration was 8.45M

Explanation:
Hello,
In this case, given the balanced reaction:
We can see a 2:4 mole ration between permanganate ion (118.9 g/mol) and manganese (IV) oxide (86.9 g/mol), that is why the resulting mas of this last one turns out:
