I would say the answer is emissions. These are the particles that are not supposed to be present in air but due to the production of different substances from humans daily activities these substances go with the air we breath. Hope this helped.
Plasma membrane is the answer
Yes, Sharpies contain volatile solvents—and when inhaled these solvents can produce a "high." The effects of inhalants (including Sharpies) can be similar to those of alcohol and include slurred speech, lack of coordination, euphoria, and dizziness.
To find molarity
We need no.of moles and solution in liter
Given data is in grams and ml
We have to convert it in required units
For no.of moles use formula
No.of mole=mass in gram / molar mass
Mass in gram = 29.1g
Molar mass = 160.4374g/mol calculated by adding the atomic wight of all atoms in LiClO4.3H2O
Atomic weight
Li= 6.941
Cl= 35.453
O= 15.9994
H= 1.00794
Now put it in mol equation
No.of mole = 29.1/160.4374
= 0.181mol of solute
Now convert solution in L from ml
235ml = 235/1000 = 0.235L
Now put these values in molarity formula
Molarity= 0.181/0.235
= 0.77M solution
