    The mass percent of chlorine can be calculated using the following rule:

    mass % = (mass of chlorine / total compound mass) * 100

    From the givens:

    mass of chlorine = 2.62 grams

    total compound mass = 2.62 + 1.37 = 3.99 grams

    Substitute in the equation to get the mass % as follows:

    mass % of chlorine = (2.62 / 3.99) * 100 = 65.6641604%
