    The cyano complex of molybdenum(V) is [Mo(CN)₈]³⁻.

    Hence, potassium molybdenum(V) cyanide is K₃[Mo(CN)₈].

    Refer to: https://www.webelements.com/

    Molor mass of K = 39.10 g/mol

    Molar mass of Mo = 95.95 g/mol

    Molar mass of C = 12.01 g/mol

    Molar mass of N = 14.01 g/mol

    Molar mass of [Mo(CN)₈]³⁻ = 39.10×3 + 95.95 + 12.01×8 + 14.01×8 = 421.41 g/mol

    % of K = (39.10×3/421.41) × 100% = 27.84%

    % of Mo = (95.95/421.41) × 100% = 22.77%

    % of C = [12.01×8/421.41] × 100% = 22.80%

    % of N = (100 - 27.84 - 22.77 - 22.80)% = 26.59%
