Note that one mole of any gas at STP occupies 22.4 L of volume. We may use this to calculate the moles of hydrogen chloride gas that need to be produced. This is:
0.0485 / 22.4
0.002 mol
Next, we see that the molar ratio between manganese chloride and hydrogen chloride in the equation is:
1 : 2
So the moles of manganese chloride reacting will be:
0.002 / 2 = 0.001 mol
The molecular mass of manganese chloride is 126 g/mol. The mass reacting will be:
0.001 * 126
0.126 grams of manganese (II) chloride will react.

Explanation:
According to Einstein the energy of photon is given by the equation,
E = hν = h . c/λ
where h is Planck's constant, c is the speed of light, ν is the frequency of light and λ is the wavelength of light.
Given, wavelength = 608 nm = 608 x 10⁻⁹ m
Conversion factor: 1 nm = 10⁻⁹ m
c = 3 x 10⁸ m/s
h = 6.626× 10⁻³⁴ J.s
Substituting the data into the equation we get,
E = h . c/λ
E = 6.626× 10⁻³⁴ J.s x (3 x 10⁸ m/s) / 608 x 10⁻⁹ m
E = 3.27 x 10⁻¹⁹J
3.27 x 10⁻¹⁹J energy must be added to strontium to get it to produce 608 nm wavelength.
