First Stability Constant Solution

Follow our step by step solution on how to calculate First Stability Constant?

FIRST Step Consider the formula

k 1 = 10^{\log 10 (\frac{n factor}{1 - n factor}) + pL}

Next Step Substitute values of Variables

∴

k 1 = 10^{\log 10 (\frac{0.5}{1 - 0.5}) + 0.3}

Next Step Prepare to Evaluate

∴

k 1 = 10^{\log 10 (\frac{0.5}{1 - 0.5}) + 0.3}

Next Step Evaluate

∴

k 1 = 1.99526231496888

LAST Step Rounding Answer

∴

k 1 = 1.9953
