In a laboratory experiment, students synthesized a new compound and found that when 14.21 grams of the compound were dissolved to make 176.3 mL of a chloroform solution, the osmotic pressure generated was 10.9 atm at 298 K. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight they determined for this compound?

a 1.043 g sample contains only vitamin C (C6H806) and sucralose (C12H19C1308). when the sample is dissolved in water to a total volume of 29.9 mL, the osmotic pressure of the solution is 4.25 atm at 303 K. what is the mass percent of vitamin C and sucralose in the sample?

The nonvolatile, nonelectrolyte chlorophyll, C55H72MgN4O5 (893.50 g/mol), is soluble in ethanol CH3CH2OH.Calculate the osmotic pressure generated when 14.6 grams of chlorophyll are dissolved in 210 ml of a ethanol solution at 298 K.The molarity of the solution is  M.The osmotic pressure of the solution is  atmospheres.

A biochemical engineer isolates a bacterial gene fragment and dissolves a 11.5-mg sample in enough water to make 30.0 mL. of solution. The osmotic pressure of the solution is 0.340 torr at 25.0 "C. Assume the gene fragment does not dissociate into multiple ions when added to the solution. Be sure each of your answer entries has the correct number of significant figures.
