Question

The molarity of a 70%(mass/mass) aqueous solution of a monobasic acid (X) is:

Hint:

To calculate molarity, you must first convert mass to moles and then use the volume of solution.

Answer 1

Correct Answer: 1.25

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 \( 1.25 \times 10^{-1} \).
