NaCl is the formula unit of sodium chloride; 0,9 NaCl is a solution, probable o,9 molar.
The solution of NaCl with the concentration 0,9 % is considered normal saline; the osmotic pressure is equal to the pressure in the cells.
Well .9 in a % would be 90%, and .09 would be 9%. So I would say yes.
0,665 moles NaCl is equivalent to 38,86 g.
The concentration is the same !
Dissolve 0,9 g sodium chloride in 100 mL distilled water.
yes
No Magnesium Sulfate (MgSO4) has a mass of 121, and Sodium Chloride (NaCl) has a mass of 59.
Both have the same cation.
Because they have same structure.(Rock salt structure)
No!
When NaCl is dissolved in a jar, it undergoes a physical change. This is because the chemical composition of NaCl remains the same, but its physical state changes from a solid to a liquid solution. The salt can be reclaimed by evaporating the liquid and it would still have the same chemical properties as the original NaCl.
Both are sodium chloride, NaCl.
