<u>Answer:</u> The energy of one photon of the given light is
<u>Explanation:</u>
To calculate the energy of one photon, we use Planck's equation, which is:
where,
= wavelength of light = (Conversion factor: )
h = Planck's constant =
c = speed of light =
Putting values in above equation, we get:
Hence, the energy of one photon of the given light is
Answer:
1.428 moles
Explanation:
If 0.0714 moles of N2 gas occupies 1.25 L space,
how many moles of N2 have a volume of 25.0 L?
Assume temperature and pressure stayed constant.
we experience it 0.0714 moles: 1.25L space
x moles : 25L of space
to get the x moles, cross multiply
(0.0714 x 25)/1.25
1.785/1.25 = 1.428 moles
