Answer:

6.1 mM

Explanation:

Osmoles counts the number of solute particles.

1.1 mM albumin will contain 1.1 milli moles of albumin per L.
2.5 mM NaCl will contain 2.5 milli moles of Na+ and 2.5 milli moles of Cl- ions per L.

Thus the total solute particles are 1.1 mmol + 2.5 mmol + 2.5 mmol = 6.1 mmol.

The total volume is 1 L.

Thus the Osmolarity is 6.1 mmoles/L or 6.1 mM
