Working on-board a research vessel somewhere at sea, you have (carefully) isolated 12.5 micrograms (12.5 ×10–6 g) of what you hope is pure saxitoxin (a non-electrolyte) from a poisonous (and quite cross) puffer fish. You dissolve this sample in 3.10 mL of water and determine that the osmotic pressure of the resulting solution is 0.236 torr at 19ºC (760 torr = 1.00 atm). What is the molar mass of the compound?
