So you have an intracellular solution with osm of 300 (nonpenetrating solutes), now if you have an extracellular osm of 300 (nonpenetrating) and 50osm of penetrating, what is the latter solution classified as:

Isotonic
Hyperosmotic
Isoosmoic
hypertonic

Answer has to contain the osmostic factor as well as the tonicity...

Thanx in advance
