  1. Question 1

    Q1. Calculate the molarity of a benzene (C₆H₆) solution if 26 g dissolves in 500 cm³ of water.

    • A) 0.4 M
    • B) 0.8 M
    • C) 1.2 M
    • D) 1.6 M

    Answer: 0.8 M

    Explanation: Molar mass C₆H₆ = 78 g/mol. 26 g = 0.333 mol. 0.333/0.5 = 0.67 M. Distractor A uses 0.333/1.
