Answer:
Atoms of sulfur = 9.60⋅g32.06⋅g⋅mol−1×6.022×1023⋅mol−1
Explanation:
because the units all cancel out, the answer is clearly a number, ≅2×1023 as required.
Explanation:
Electromagnetic wave Wavelength
(1) Microwave = 1 m to 1 mm =
to ![10^6 nm](https://tex.z-dn.net/?f=10%5E6%20nm)
(2) Ultraviolet = 10 nm to 400 nm
(3) Radio waves = 1 mm to 100 km =
to ![10^{14}nm](https://tex.z-dn.net/?f=10%5E%7B14%7Dnm)
(4) Infrared = 700 nm to 1 mm
(5) X-ray = 0.01 nm to 10 nm
(6) Visible = 400 nm t0 700 nm
a) In order of increasing wavelength:
: 5 < 2 < 6 < 4 < 1 < 3
b) Frequency of the electromagnetic wave given as:
![\nu=\frac{c}{\lambda }](https://tex.z-dn.net/?f=%5Cnu%3D%5Cfrac%7Bc%7D%7B%5Clambda%20%7D)
= frequency
= Wavelength
c = speed of light
![\nu \propto \frac{1}{\lambda }](https://tex.z-dn.net/?f=%5Cnu%20%5Cpropto%20%5Cfrac%7B1%7D%7B%5Clambda%20%7D)
So, the increasing order of frequency:
: 3 < 1 < 4 < 6 < 2 < 5
c) Energy(E) of the electromagnetic wave is given by Planck's equation :
![E=h\nu](https://tex.z-dn.net/?f=E%3Dh%5Cnu%20)
![E\propto \nu](https://tex.z-dn.net/?f=E%5Cpropto%20%5Cnu)
So, the increasing order of energy:
: 3 < 1 < 4 < 6 < 2 < 5
