    Study Notes

    Unità de Concentration Commun

    • Molarity: number de moles de solute per litro de solution, generalmente usate pro liquidos.
    • Molality: moles de solute per kilogramma de solvente, utile in systemas con varientia de temperatura.
    • Mass Percent: massa de solute per massa total de solution multiplicate per 100, pertinent pro solutiones solide.

    Prefixes Metric

    • Giga (G): 10^9
    • Mega (M): 10^6
    • Kilo (k): 10^3
    • Hecto (h): 10^2
    • Deka (da): 10^1
    • Deci (d): 10^-1
    • Centi (c): 10^-2
    • Milli (m): 10^-3
    • Micro (μ): 10^-6
    • Nano (n): 10^-9
    • Pico (p): 10^-12
    • Femto (f): 10^-15
    • Atto (a): 10^-18
    • Zepto (z): 10^-21
    • Yocto (y): 10^-24

    Error Types

    • Systematic Error: bias, determinate error, correctable, de un solo lato; minimizable con una metodologia precise.
    • Random Error: varia fortuito, influence in tutte le replicaciones; reducibile per aumentar le dimension del sample.
    • Gross Error: errores extrem, resultante de fallos de instrumenta o contamination del sample.

    Propagation de Incertezza

    • Addition and Subtraction: usa incertezza absolute, includente unitates.
    • Multiplication and Division: usa incertezza relative, applicabile a valores misurate.

    Accuratezza e Precision

    • Accuratezza: prope del valore mesurate al valore vere; frequentemente non cognoscite.
    • Precision: reproductibilitate de misurationes; menzionate como variation inter misurationes multiple.
