Answer: The energy of a mole of photon associated with this frequency is 
Explanation:
The energy and frequency are related by :

E = energy of photon
N = number of moles = 1
h = planks constant = 
= frequency = 

The energy of a mole of photon associated with this frequency is 
For i: 33mL
For ii: 87-88mL
For iii:22.3mL
Answer:
Here's what I get
Explanation:
The Lewis structure of SO₃ consists of a central sulfur atom double-bonded to each of three oxygen atoms that points to the corners of an equilateral triangle.
A ball-and-stick model of SO₃ is shown below.
