What is the mass of 2.00 l of an intravenous glucose solution with a density of 1.15 g/ml?

How many moles is 14.5 cm^3 of platinum? the density of platinum is 21.45 g/cm^3.

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
