Here is how the Acid Value of KOH equation looks like.

0.2806 = 56.11 \cdot 15 \cdot \frac{0.5}{1.5}

0.2806g = 56.11g/mol \cdot 15mL \cdot \frac{0.5}{1.5g}

0.2806 = 56.11 \cdot 15 \cdot \frac{0.5}{1.5}

Acid Value of KOH Solution

Follow our step by step solution on how to calculate Acid Value of KOH?

FIRST Step Consider the formula

AV = M w \cdot V \cdot \frac{N}{W s}

Next Step Substitute values of Variables

∴

AV = 56.11g/mol \cdot 15mL \cdot \frac{0.5}{1.5g}

Next Step Convert Units

∴

AV = 0.0561kg/mol \cdot 1.5E-5m³ \cdot \frac{0.5}{0.0015kg}

Next Step Prepare to Evaluate

∴

AV = 0.0561 \cdot 1.5E-5 \cdot \frac{0.5}{0.0015}

Next Step Evaluate

∴

AV = 0.00028055kg

Next Step Convert to Output's Unit

∴

AV = 0.28055g

LAST Step Rounding Answer

∴

AV = 0.2806g
