When diluting solutions from concentrated solutions the following formula can be used
c1v1 = c2v2
where c1 is concentration and v1 is volume of the concentrated solution
and c2 is concentration and v2 is volume of the diluted solution to be prepared
substituting these values
0.0813 M x 16.5 mL = 0.0200 M x V
V = 67.1 mL
the volume of the diluted solution prepared is 67.1 mL.
the volume of water that should be added to get a final volume of 67.1 mL is (67.1 - 16.5 ) = 50.6 mL
a volume fo 50.6 mL should be added
Radio waves, microwave, infrared, visible light, ultra violet, X-rays, gamma rays. that is lowest to highest and i no it is right mark as brainliest please
We Know, Velocity of light = frequency * wavelength
frequency = velocity/wavelength
f = 3 * 10⁸ / 6.50 * 10⁻⁷
f = 4.61 Hertz
So, your final answer is 4.61 Hz
Hope this helps!

Answer:
Explanation:
molar mass of BaCl2 = 208.23
mol of BaCl2 = 8/208.22
mol of BaCl2 = 0.03841905
Molarity = 0.03841905/0.450
Molarity = 0.085 M
