Question

A certain bacterium measures 2. 7 × 10–2 mm. A colony contains 5. 3 × 103 of the bacteria. What is the total length of this colony if it forms a straight line?

Answer 1

The length of the colony is the product of 5. 3 × 10^3 and the length of the bacteria

The total length of the colony is 143.1 mm

How to determine the length of the colony?

The given parameters are:

Bacteria = 2.7 × 10^–2 mm.

Colony = 5. 3 × 10^3 of the bacteria

So, the length (L) of the colony is:

$L = 5.3 * 10^3 * 2.7 * 10^{-2$

Rewrite as:

$L = 5.3 * 2.7* 10^3 * 10^{-2$

Evaluate the products

$L = 14.31* 10$

Evaluate the product

$L = 143.1$

Hence, the total length of the colony is 143.1 mm
