Compare the wavelengths of infrared waves, ultraviolet rays, and visible light. ... UV rays have shorterwavelengths and higher frequencies than visible light waves do.
Answer:
[Ag+] = [NO3-] = 0.700M
0.555M = [Na+] = [I-]
Explanation:
To solve this question we need to find the moles of sodium iodide, NaI, using its molar mass -. With the moles and the volume we can find the molarity of Na+ and I-. The molarity of the ions of silver nitrate, AgNO3 doesn't change because we are assuming the volume doesn't change:
<em>Molarity Ag⁺ = Molarity NO₃⁻ = 0.700M</em>
<em>Moles NaI -Molar mass: 149.89g/mol-</em>
20.8g NaI * (1mol/149.89g) = 0.0139 moles NaI
<em>Molarity:</em>
0.0139 moles NaI / 0.250L = <em>0.555M = [Na+] = [I-]</em>
