Plasma osmolarity is 275-300 mosm/L
{ (0.0296 g NaCl) / (1 L soln) } x { (1 mol NaCl) / (59 g NaCl) } x { (2 osm) / (1 mol NaCl) } = 1 mosm/L
{ (0.0264 g glc) / (1 L soln) } x { (1 mol glc) / (180 g glc) } x { (1 osm) / (1 mol NaCl) } = 150 mosm/L
You can do the rest, pro forma.
Crenelates in hypertonic solution, lyses in hypotonic solution.
