Dilution Factor of Bacteria Solution

Follow our step by step solution on how to calculate Dilution Factor of Bacteria?

FIRST Step Consider the formula

DF = \frac{CFU \cdot v c}{n c}

Next Step Substitute values of Variables

∴

DF = \frac{14Cells/L \cdot 10m³}{9}

Next Step Convert Units

∴

DF = \frac{14000Cells/m³ \cdot 10m³}{9}

Next Step Prepare to Evaluate

∴

DF = \frac{14000 \cdot 10}{9}

Next Step Evaluate

∴

DF = 15555.5555555556

LAST Step Rounding Answer

∴

DF = 15555.5556
