    Average Atomic Mass = 63.5460 amu

    Explanation:

    Data Given:

    Atomic Mass of ⁶³X = 62.9296 amu

    Natural Abundance of ⁶³X = 69.15 %

    Atomic Mass of ⁶⁵X = 64.9278 amu

    Natural Abundance of ⁶⁵X = 30.85 %

    Formula Used:

    Average Atomic Mass = [ (Atomic Mass of ⁶³X * Natural Abundance of ⁶³X) + (Atomic Mass of ⁶⁵X * Natural Abundance of ⁶⁵X) ] : 100

    Putting values,

    Average Atomic Mass = [ (62.9296 * 69.15) + (64.9278 * 30.85) ] : 100

    Average Atomic Mass = [ (4351.5818) + (2003.0226) ] : 100

    Average Atomic Mass = 6354.6044 : 100

    Average Atomic Mass = 63.5460 amu
