Explanation:
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, 
Answer:
147.6 mL .
Explanation:
sodium carbonate , Na₂CO₃
Molecular weight = 106
3.55 gm of sodium carbonate = 3.55 / 106
= .0335 moles
Let the volume of litre required = V
V litre of .227 M solution will contain
V x .227 moles of sodium carbonate . So
V x .227 = .0335
V = .1476 L
= 147.6 mL .
Answer:
Ionic bonds ussally form with a metal, and a non metel elements, so the answer would most likley be B.
