A bacterial cell measures 2.5 micrometers (µm) in length. What is the size of this cell in nanometers (nm)?

250 nm

Explanation:

Data provided in the question:

Length of the bacteria cell = 2.5 micrometers (µm)

Now,

We know that,

1 m = 10⁶ µm

or

1 µm = 10⁻⁶ m

also,

1 m = 10⁹ nm

or

10⁻⁹ m = 1 nm

Therefore according to the above results we get,

2.5 micrometers (µm) = 2.5 × 10⁻⁶ m

and,

2.5 × 10⁻⁶ m = ( 2.5 × 10⁻⁶ ) × 10⁹ nm

= 2.5 × 10³

= 250 nm

halogen, any of the six nonmetallic elements that constitute group 17 (group viia) of the periodic table. the halogen elements are fluorine (f), chlorine (cl), bromine (br), iodine (i), astatine (at), and tennessine (ts).
