Answer:
1. the absolute pressure in the tank before filling = 217 kPa
2. the absolute pressure in the tank after filling = 312 kPa
3. the ratio of the mass after filling M2 to that before filling M1 = 1.44
The correct relation is option c ()
Explanation:
To find -
1. What is the absolute pressure in the tank before filling?
2. What is the absolute pressure in the tank after filling?
3. What is the ratio of the mass after filling M2 to that before filling M1 for this situation?
As we know that ,
Absolute pressure = Atmospheric pressure + Gage pressure
So,
Before filling the tank :
Given - Atmospheric pressure = 100 kPa , Gage pressure = 117 kPa
⇒Absolute pressure ( p1 ) = 100 + 117 = 217 kPa
Now,
After filling the tank :
Given - Atmospheric pressure = 100 kPa , Gage pressure = 212 kPa
⇒Absolute pressure (p2) = 100 + 212= 312 kPa
Now,
As given, volume is the same before and after filling,
i.e. =
As we know that, P ∝ M
⇒
⇒
⇒ ≈ 1.44
Now, as we know that PV = nRT
As V is constant
⇒ P ∝ MT
⇒ ∝ M
⇒
So, The correct relation is c option.

Explanation:
Lewis dot structures represent the symbol of an atom we're looking at and the number of valence electrons it has. This number is represented by the sum of dots around the symbol.
- Potassium is in group 1A, this means it only has one valence electron, so we draw K with one dot in its Lewis diagram;
- Argon is in group 8A, this means it has eight valence electrons, so we draw Ar with 8 dots around it in its Lewis diagram;
- Silicon is in group 4A, this means it has four valence electrons, so we draw Si with 4 dots around it in its Lewis diagram;
- Arsenic is in group 5A, this means it has five valence electrons, so we draw As with 5 dots around it in its Lewis diagram.
Those are represented in the image attached below:
