They will most likey group with the second group. Since they have 6 electrons and want to have a full outer shell so therefore would group with the second group.
According to the Heisenberg uncertainty principle, which of the following statements about the simultaneous measurements of position and momentum is true?a.Neither quantity can be measured with accuracy.b.The more accurately one value is measured, the less accurately the other value is known.c.Both quantities can be measured with infinite accuracy.d.Accuracy of measurement improves as the object observed becomes less massive. yeah so the answer is b sorry i copied and paste i just wanted to make it fast :(
When there is change of state solid to liquid to gas or in any order then there will be change in intermolecular bonds. amount of intermolecular bonds.
The molar mass of the compound:
If the solution has an osmotic pressure of 8.44 torr, then the molar mass of the unknown non-electrolyte is 223.14 g.
What is osmosis?
- Osmosis is defined as the flow of solvent molecules through semi-permeable membrane.
- Osmotic pressure is the pressure applied to stop the flow of solvent molecules.
- It is a colligative property that means osmotic pressure depends on the number of solute particles .
Therefore,
π ( for electrolytes)
Where, π= Osmotic pressure
i = Van 't Hoff factor
n= moles
R= Gaseous constant = 62.363577 L torr
T= Temperature
V= Volume of solution
Given:
T= 298K
V= 150 mL= 0.150 L
Given mass of unknown electrolyte= 15.2 mg = 15.2 x g
Osmotic pressure= 8.44 torr
Molar mass= ?
For non-electrolytes:
πV = n RT
πV=RT
Calculations:
Putting the given values in the formula:
8.44 x 0.150 =15.2 x / M x 62.36 x 298
1.266 = 282.5/M
M = 282.5/1.266
M = 223.14 g
Therefore,
The molar mass of the unknown non-electrolyte is 223.14g.
