Question
The typical length of a bacteria is 0.5 μ. How many bacteria are there in 1 m length? [Ans. 2 × 106]
Answer
Length of a bacteria = 0.5 μm
We need to find the number of bacteria in 1 m length.
We can start by converting the length of a bacteria from micrometres to meters:
0.5 μm = 0.5 × 10-6 m
Next, we can divide the total length of 1 m by the length of a single bacteria in meters:
Number of bacteria in 1 m = 1 \over 0.5 × 10^{-6}
Number of bacteria in 1 m = 2 × 106 bacteria
Therefore, there are 2 × 106 bacteria in 1 m length.
