The energy of the photon with the wavelength of 584 nm is 3.4×10¯¹⁹ J
<h3>How to determine the frequency of the photon</h3>
- Wavelength (λ) = 584 nm = 584×10⁻⁹ m
- Speed of light (v) = 3×10⁸ m/s
- Frequency (f) = ?
f = v / λ
f = 3×10⁸ / 584×10⁻⁹
f = 5.14×10¹⁴ Hz
<h3>How to determine the energy</h3>
- Planck's constant (h) = 6.626×10¯³⁴ Js
- Frequency (f) = 5.14×10¹⁴ Hz
- Energy (E) =?
E = hf
E = 6.626×10¯³⁴ × 5.14×10¹⁴ Hz
E = 3.4×10¯¹⁹ J

Answer:
ρ = 2.07 g/mL
Explanation:
Step 1: Given data
- Mass of the block G (m): 49.231 g
- Volume of the block G (V): 23.8 mL
Step 2: Calculate the density (ρ) of the block G
The density is an intrinsic property, equal to the mass of the block divided by its volume.
ρ = m/V
ρ = 49.231 g/23.8 mL
ρ = 2.07 g/mL
The density of the block G is 2.07 g/mL.
The answer is: " S²⁻ " .

Your answer would be,
Molarity = moles of solute/volume of solution we needed, 29.22(g)(mol) of NaCI
= 29.22(g)/58.44(g)(mol^-1)(1)/1(L)
= 0.500(mol)(L^-1)
Hope that helps!!!
