How much energy in kJ is associated with a radio wave of wavelength 1.2 X 10^2 m?

eduard

It's very simple.

Energy = $\frac{hc}{\lambda}$

where, h= Planck's constant = 6.6 x $10^{-34}$ $m^2 kg/s$

c= speed of light = 3 x $10^{8}$ m/s
$\lambda$ = wavelength

So, energy = $\frac{6.6 \times 10^{-34} \times 3 \times 10^{8}}{120}$

= 1.65 x $10^{-27}$ J
=1.65 x $10^{-30}$ KJ

The mass of solute per 100 mL of solution is abbreviated as (m/v). Mass is not technically the same thing as weight, but the abbreviation (w/v) is also common. 262 grams of sucrose are needed to make 655 mL of a 40.0% (w/v) sucrose solution

<h3>Define Solute</h3>

A solute is a material that dissolves in a solution. The amount of solvent present in fluid solutions is greater than the amount of solute. The two most common examples of solutions in daily life are salt and water. Salt is the solute because it dissolves in water.

<h3>forms of ratios for product concentration or yield:-</h3>

w/v:- Weight by volume or weight per volume are the terms used. Any solid compound's concentration in a liquid can be calculated using it. It is measurable in gm/ml.

Weight by weight ratio is referred to as w/w.It is employed to determine the final yield of the compound obtained from the starting compound. as in —mg/—gm.

It provides the real yield of the substance or item.
