Osmolarity The
feedback loop of sweat loss is to feel thirsty and reach out for a drink.
Prerna did the same. She had a bottle of
water as well as a fruit juice.
The following figure shows the nutritional information of the fruit juice. Assume that the
primary contributors for the osmolarity are sodium, potassium and total sugars; the total sugars in the juice are in the form of glucose. Atomic
mass of sodium = 23 g/mol, atomic mass of potassium of 39 g/mol, molar mass of
glucose = 180 g/mol.

Osmolarity
is a colligative property, meaning it depends on the total number of solute
particles in a solvent and not on their chemical identity. The plot on the
right shows the major solutes present in our body fluids. Given this
information, choose all the correct options.

Answer

Osmolarity
of ECF is  around 300 OsM, and the orange
juice has an osmolarity hypertonic to the body’s ECF

Answer

Osmolarity
of the orange juice is about 700 mOsM, and the orange juice is hypertonic to
the body’s ECF

Answer

Osmolarity of the ECF is around 300 mOsM, and the
orange juice is hypotonic to the body’s ECF

Answer

Osmolarity of the orange juice and the ECF
are both about 500 mOsM.

Answer

Osmolarity of the orange juice is about 200
mOsM, and it is hypotonic to the body’s ECF

Answer

Osmolarity of orange juice is 400 mOsM, and
that of ECF is 300 mOsM.
