Solutions of two (2) non-electrolytes are prepared by dissolving 0.1398 grams of each compound in enough water to make 25.0 mL of solution. The solutions are placed on either side of a u-tube and are separated by a semipermeable membrane that only allows water to pass. After a period of time, the u-tube looks like this: u-tube Based on this data we know: (select all that apply) The molar mass of the solute in solution B is larger. The osmotic pressure of solution B is higher. The molar mass of the solute in solution A is larger. The concentration of particles is higher in solution B. The osmotic pressure of solution A is higher.
