No. of Colonies of Bacteria Solution

Follow our step by step solution on how to calculate No. of Colonies of Bacteria?

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

n c = \frac{14Cells/L \cdot 10m³}{7}

Next Step Convert Units

∴

n c = \frac{14000Cells/m³ \cdot 10m³}{7}

Next Step Prepare to Evaluate

∴

n c = \frac{14000 \cdot 10}{7}

LAST Step Evaluate

∴

n c = 20000
