    The mass of hexane is 364 grams

    Explanation:

    Step 1: Data

    Density = 655 g/L

    Volume = 555 mL

    Step 2 Convert the volume from mL to L

    555 mL = 555 * 10^-3 L = 0.555 L

    Step 3: Calculate mass

    Density = mass hexane / volume

    Mass hexane = density * volume

    Mass hexane = 655 g/L * 0.555 L

    Mass hexane = 364 grams

    The mass of hexane is 364 grams
