Mercury's atomic emission spectrum is shown below. estimate the wavelength of the dark green line. what is its hz what is the energy of an dark green photon emitted by the mercury atom?

Explanation:

From the atomic emission spectrum of Mercury, the wavelength of the dark green line is 545 nm.

The relation between the frequency and wavelength is given by :

Let E is the energy of an dark green photon emitted by the mercury atom. It is given by :

h is Planck's constant

Hence, this is the required solution.

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
