  1. Question 1

    Q1. A 20 mL sample of an aqueous solution of phenol (C6H5OH) contains 0.5 g of phenol. What is the molar concentration of phenol in the solution?

    • A) 0.02 M
    • B) 0.1 M
    • C) 0.2 M
    • D) 0.4 M

    Answer: 0.2 M

    Explanation: The molar concentration of phenol can be calculated using the formula: Molarity = moles of solute / liters of solution, which equals 0.2 M in this case.
