Answer:
n=5
Explanation:
Applying the Rydberg's equation
hc/l= RH[(1/nf^2)-(1/ni^2)
Let l= wavelength= 3745×10^-9m
h=6.63×10^-34 , c= 3.0×10^8, RH= 2.179×10^-18
Substitute into the Rydberg's equation and simplify
(6.63×10^-34×3×10^8)/3745×10^-9=2.179×10^-18(1/nf^2 -1/8^2)
0.024= 1/nf^2 -0.0156
0.024+0.0156= 1/nf^2
0.0396= 1/nf^2
nf^2= 25.3
Take square root of both sides
nf= 5.02=5

Average location of the Pacific and Polar Jet Streams and typical temperature and precipitation impacts during<span> the winter over North </span>America<span>.</span>
The volume of Iron (in cm^3) = 4840/7.86 = 615.78 cm^3.
1 cm^3 = 1 mL and there are 1000 mL in 1 dL
So to convert from cm^3 to dL, we just have to divide by a 1000
615.78/1000 = 0.61578 dL
