The molarity of the solution is 0.1625M.
<h3>What do you meant by Molarity</h3>
Molarity is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of solute per litres of a solution .
Molarity → no of moles / Volume (L)
SI unit of Molarity is M or mol/ L
We have given here the mass of solution is 3.10×10²g .
molality of the solution is 0.125m
Molality → no of moles / mass in kg
→ 0.125×3.10×10²/ 1000
→ no.of moles = 0.0162
For molarity we can assume volume as 1000 ml .
Molarity = 0.0162×1000/ 100
Molarity →0.162 M.
So, the molarity of solution will be 0.162M.

Answer:
I think its the first one. unless there is more to the question
The unit expressed in 660 nm of light represents the wavelength of light. If you want to determine the frequency, you use the speed of light to relate the two. The formula is:
c = λν
where
λ is the wavelength
ν is the frequency
c is the speed of light = 3×10⁸ m
Apply SI units:
(3×10⁸ m) = (660×10⁻⁹ m)(ν)
Solving for ν,
<em>ν = 4.55×10¹⁴ s⁻¹</em>
