What is the energy of an electromagnetic wave with a frequency of 8•10^12 Hz?
aniked [119]

Hello!

Find the Energy of the Photon by Planck's Equation, given:

E (photon energy) =? (in Joule)

h (Planck's constant) = 6.626*10^{-34}\:J * s

f (radiation frequency) = 8*10^{12}\:Hz

Therefore, we have:

E = h*f

E = 6.626*10^{-34}*8*10^{12}

E = 53.008*10^{-34+12}

E = 53.008*10^{-22}

\boxed{\boxed{E = 5.3008*10^{-21}\:Joule}}\end{array}}\qquad\checkmark

I Hope this helps, greetings ... DexteR! =)

What is the relative formula mass of N2O? Ar of N = 14 and Ar of O = 16.
s2008m [1.1K]

We have to calculate formula mass of N₂O.

The answer is: 44

Relative formula mass is the sum of relative atomic mass of constituent atoms in a formula unit of any compound.  Relative formula mass is represented as same symbol of relative molecular mass.

To calculate relative formula mass we need to know number of each atom in the formula and then adding atomic masses of all the atoms.

In N₂O, number of N-atom present is equal to 2 and number of O-atom is equal to  1.

Atomic mass of N-atom is 14 and atomic mass of O-atom is 16.

So, formula mass of N₂O is (2 X 14)+16 = 44.
