Answer : The molar mass of protein is, 
Explanation :
Formula used :

where,
= osmotic pressure = 0.138 atm
C = concentration
R = solution constant = 0.0821 L.atm/mol.K
T = temperature = 
w = mass of protein subunit = 0.155 g
M = molar mass of protein subunit = ?
V = volume of solution = 2.00 mL
Now put all the given values in the above formula, we get:



Therefore, the molar mass of protein is, 
Explanation:
Magnesium chloride = MgCl₂
aluminum nitrate= Al(NO₃)₃
ammonium sulfate=( NH₄)₂SO₄
Answer:
nitrogen, oxygen, argon, carbon dioxide, neon, helium, krypton, hydrogen, and xenon. It does not include water vapor because the amount of vapor changes based on humidity and temperature.
