Can anyone help me with the calculations for the Frequency, Wavelength, Energy Chart?
1 answer:
Use the following equations to fill the chart.
E = hf
where
h = 6.63 x 10⁻³⁴ J/s, Planck's constant
f = frequency Hz
E = quanta of energy, J
c = fλ
where
c = 3 x 10⁸ m/s, the velocity of light
λ = wavelength, m
If energy is given in J/mmol, divide by Avogadro's number, N = 6.02 x 10²³, to convert it to J.
The completed table is shown below.

Answer:
0.22L
Explanation:
Given parameters:
Concentration of solution = 4.00M
Mass of lithium Bromide = 75g
Unknown:
Volume of water = ?
Solution:
Concentration in terms of the molarity is the number of moles of solute in a solution.
Molarity =
let us find the number of moles first;
Number of moles =
Molar mass of LiBr = 7 + 80 = 78g/mol
number of moles =
number of moles = 0.96moles
Volume of water = = 0.96/4 = 0.22L
