Correct Answer: 1.25
Solution and Explanation
Step 1: Given density and molar mass of the acid, calculate the molarity using the formula:
\[
\text{Molarity} = \frac{\text{Mass of solute}}{\text{Volume of solution in L}}
\]
Step 2: Apply the given values and compute the molarity.
Final Conclusion:
The molarity is \( 1.25 \times 10^{-1} \).
