The molarity of the zinc chloride solution will be 0.089 M

<h3>Molarity</h3>

Mole of 7.24 g ZnCl2 = 7.24/136.286 = 0.5312 mol

Total volume of water used in preparing the solution = 300 + 300 = 600 mL

Molarity of the solution = mole/volume = 0.5312/0.6 = 0.089 M

The molarity of the zinc chloride solution is, therefore, 0.089 M

30 POINTS PLEASE HELP ASAP

lina2011 [118]

Hello!

We have the following data:

f (radiation frequency) = $3.0*10^{19}\:Hz$

v (speed of light) = $3.0*10^8\:m/s$

λ (wavelength) = ? (in m)

Let's find the wavelength, let's see:

$f = \dfrac{v}{\lambda}$

$3.0*10^{19} = \dfrac{3.0*10^8}{\lambda}$

$\lambda = \dfrac{3.0*10^8}{3.0*10^{19}}$

$\boxed{\boxed{\lambda = 1*10^{-11}\:m}}\Longleftarrow(wavelenght)\end{array}}\qquad\checkmark$

I Hope this helps, greetings ... DexteR! =)
