I had to use an eyewash after the sand blew in my face.
Using an eyewash that is produced to be used as such is safe, if used according to the directions. Homemade eyewashes may be harmful. It is always best to use an approved eyewash.
Eyewash bottles are suitable for use only between the time you get a corrosive chemical in your eye and when you get to an eyewash fountain. Asbestos is not a corrosive chemical. If it gets into your eye, it will not be more damaging than other forms of dust, so there is no need for such a device, and little value.
The solution of NaCl with the concentration 0,9 % is considered normal saline; the osmotic pressure is equal to the pressure in the cells.
Eyewash is used to get debris out of the eye. Like if your eye felt like something got into it and it was hurting then you would need to use eyewash or just rinse your eye with water to remove whatever had gotten into it.
Well .9 in a % would be 90%, and .09 would be 9%. So I would say yes.
You can purchase a certified eyewash station at www.uline.com/Eyewash-Station.
The answer is 0,9 g pure, dried NaCl.
it is acetylsalcylic acid

The answer is 26,3 g.
To determine the number of moles of NaCl, you need to know the mass of NaCl you have and the molar mass of NaCl (58.44 g/mol). You can then use the formula moles = mass / molar mass to calculate the number of moles of NaCl.
