    Mass percentage of analyte = 0.10%

    Explanation:

    The mass of analyte in the solution is calculated as follows:

    n = CV = (21.1 mgL⁻¹) (100 mL) (1L/1000mL) = 2.11 mg

    The mass percentage of the analyte is calculated as follows:

    (g analyte) / (g sample) x 100%

    (2.11 mg) (1g/1000g) / (2.05g) x 100% = 0.10%
