Number of moles = 0.0688 moles of NaoH

volume = 0.250 L

Molarity = moles of solute / volume ( L )

M = 0.0688 / 0.250

M = 0.28 M

Select the correct answer. The wavelength of a given region of the electromagnetic spectrum ranges from 1 x 10-11 - 1 x 10-8 met
Makovka662 [10]

X-rays are found in the given region.

Answer: Option B

<u>Explanation:</u>

The wavelengths of different waves are studied carefully, and their range is determined according to the frequency they exhibited. And based upon the studies, the electromagnetic waves are classified into eight different categories such as gamma, X-, UV, visible, near IR, middle IR, far IR, micro and radio waves.

And each category has different wavelengths and the given radiation falls under X-rays.  The wavelength range of X-rays varies from 1 nm to 1 pm. Here, “nm” stands for nano meter and “pm” stands for “pico meter”.
