1) Molarity
M = n / V
n: number of moles of solute
V: volume of the solution in liters
n = mass / molar mass = 0.000333 g / 332.32 g / mol = 1*10 ^ - 6 moles
V = 225 ml * 1 liter / 1000 ml = 0.225 liter
M = 10^-6 mol / 0.225 liter = 0.00000444 M
2) ppm
ppm = parts per million
grams of solute: 0.000333 g
grams of solution = volume * density = 225 ml * 0.785 g / ml = 176.625 g
ppm = [0.00033 g / 176.625 g] * 1,000,000 = 1.868 ppm
The true structure of HCONH2 is a resonance hybrid of two structures.
Linus Pauling introduced the idea of resonance to explain the observed properties and bond lengths of some compounds.
Resonance occurs where there is a movement of electrons within a molecule. This electron redistribution affects properties of the molecule such as bond lengths and bond distances.
Since the lone pair on the nitrogen of the amine group participates in resonance with the carbonyl moiety in the molecule, a resonance is set up as shown in the image attached to this answer.
This resonance accounts for the fact that the HCONH2 has been shown to have a bond length that is in between a typical C-N single bond and a C=N double bond.

Sorry but don't get it (no offense; will figure out later)
Answer:
Explanation:
The Car and The Wall
According to Newton's first law, an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force. ... Any passengers in the car will also be decelerated to rest if they are strapped to the car by seat belts.
When the car makes contact with the barrier, there is reaction of equal magnitude that arises from the car making contact with the barrier. The reaction force is easily visible in a car crash, which is why it is such a great way to show how Newton's Third Law can be applied to our lives.
