Finding the osmolarity, A drug that does not dissociate has

The osmolarity of human plasma is normally 290 milli-osmoles per liter (0.29 Osmolar). Use a value of 300 milliosmoles/liter (300 mOsM) in solving the problems below.
1. A drug that does not dissociate has a molecular weight of 300. If 300 g of this drug are dissolved in 1000 ml of water, what is the osmolarity (in Osmols/liter or mOsmols/liter) of the resulting solution?
