Calculate the energy of a photon with a frequency of 2.36 x 10-19 Hz.
OlgaM077 [116]

Answer:

Explanation:

energy for photon is calculated in same wasy as for electromagnetic radiation

energy for electromagnetic radiation = hf

where f is the frequency of photon

h is Planck's constant = h = 4.14 × 10−15 eV · s.

thus

energy of photon = 4.14 × 10−15 eV · s *  2.36 x 10-19 Hz

energy of photon = 9.77 * 10−(-15+ -19) eV

energy of photon = 9.77 * 10−34eV        answer

How many moles are in 123.0g (NH4)2SO4
Luda [366]
Here you go! There are 0.9307 moles in 123.0 g of the compound. I solved this by using a fence post method. I calculated the number of grams in one mol of (NH4)2 SO4 and got 132.16.

I did this by finding the atomic mass of each element on the periodic table (my work is in the color blue for this step)

After that, i divided the given mass by the mass of one mol of the compound.

The answer is 0.9307 moles!! I hope this helped you! :))
