Question

Solution Osmolarity relative to RBC before blood is added (Isosmotic? Hyperosmotic? Hyposmotic?) Osmolarity relative to RBC after blood is added (Isosmotic? Hyperosmotic? Hyposmotic?) Tonicity relative to RBC (Isotonic? Hypertonic? Hypotonic?) 0.1 M Sucrose Solution Osmolarity relative to RBC before blood is added (Isosmotic? Hyperosmotic? Hyposmotic?) Osmolarity relative to RBC after blood is added (Isosmotic? Hyperosmotic? Hyposmotic?) Tonicity relative to RBC (Isotonic? Hypertonic? Hypotonic?) 0.1 M Sucrose

Explanation / Answer

Answer

Here the osmolarity of the sucrose is 0.2 osmol/L

Sucrose = fructose + Glucose (for 0.1 M)

= 0.1 + 0.1 = 0.2 Osmoles

so 0.1 M sucrose is hyposmotic

The osmolarity of the blood is 0.295 Osmol/ L

When added to the blood, The osmolarity is more indicate hyperosmotic.

The tonicity relative to RBC is Hypotonic

Solution Osmolarity relative to RBC before blood is added (Isosmotic? Hyperosmotic? Hyposmotic?) Osmolarity relative to RBC after blood is added (Isosmotic? Hyperosmotic? Hyposmotic?) Tonicity relative to RBC (Isotonic? Hypertonic? Hypotonic?) 0.1 M sucrose Hyposmotic Hyperosmotic Hypotonic
