Feliz [49]

Answer:

cumulative dilution = 0.000001

Explanation:

A serial dilution is a stepwise kind of dilution repeated a certain number of times, in which the concentration reduces exponentially each time.

The cumulative dilution is the final dilution gotten depending on the number of times dilution has been done and the dilution factor. The formula is given as:

Cumulative dilution = (F)ⁿ

where:

F = dilution factor = 0.1

n = number of serial dilutions = 6

∴ cumulative dilution = (0.1)⁶ = 0.000001
