We know, E = Planck's constant * speed of light / wavelength
Here, h = 6.62607004 × 10-34 m2 kg / s
c = 3 * 10^8 m/s
w = 4966.36 nm = 4966.36 * 10^-9m = 4.96636 * 10^-6 m
Substitute their values,
E = (6.62607004 × 10-34) (3 * 10^8) / (4.96636 * 10^-6)
E = 19.88 × 10^-26 / 4.96636 * 10^-6
E = 4 × 10^-20 J
E = 4 × 10^-20 / 10^3
E = 4 × 10^-23 KJ
In short, Your Answer would be: 4 × 10^-23 KJ
Hope this helps!

Explanation:</h3>
The new kind of matter is a liquid since the solid juice bar has melted. But it is <u>not</u> a new substance.
<em>Hope you got this correct!</em>
1mol ------------ 3×6,02×10²³ oxygen atoms
x ------------ 2,55×10²⁴
x = 2,5×10²⁴ × 1mol / 3×6,02×10²³ ≈ 0,138*10 mol = 1,38mol
