The waters of the Dead Sea are extremely saline, and, generally, the concentration of salt increases toward the lake's bottom. ... The deep water was saturated with sodium chloride , which precipitated to the bottom.
Answer:
0.67mol/Kg
Explanation:
The following were obtained from the question:
Mole of solute = 0.50mol
Mass of solvent = 750g = 750/1000 = 0.75Kg
Molality =?
Molality = mole of solute /mass of solvent
Molality = 0.5/0.75
Molality = 0.67mol/Kg
Answer:
False.
Explanation:
Technically it's false although many people think it is true. The property measured by temperature is Kinetic Energy. Temperature measures how fast particles are moving.
Answer: New concentration of 
is 0.23 M.
Explanation:
The given data is as follows.
Moles of = 0.06 mol
Moles of 
= 0.08 mol
Therefore, moles of 
added are as follows.
Moles of = 
= 0.003125 mol
Now, new moles of = 0.06 + 0.003125
= 0.063125
Therefore, new concentration of will be calculated as follows.
Concentration = 
= 0.23 M
Thus, we can conclude that new concentration of is 0.23 M.
