Share ody) Shapes Cunvert Sinartt Picture Tet Be tioe Arrange Ou An smotic pressure of 954mmHg is measured for i.OL solution of 1.50g MCI(aq) at 25°C. What is the ion Mt? Again, this is a challenging problem, so I will not ask what is the first digit. Do give it some thought and try to solve it. Start by listing the steps which will need to be taken. We will, of course, do it in class.

The freezing point of benzene, C6H6, is 5.500 °C at 1 atmosphere. Kf(benzene) = -5.12 °C/m In a laboratory experiment, students synthesized a new compound and found that when 11.50 grams of the compound were dissolved in 250.5 grams of benzene, the solution began to freeze at 4.685 °C. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight they determined for this compound ? g/mol

For an aqueous solution of HF, determine the van't Hoff factor assuming 0% ionization.

I want the solution in a schematic drawing not in word form please

A. (see pic) B. When an electrolyte solution (such as NaCl) is added to ice, the ions have ____ with water molecules and thus ____ the ability of the water molecules to form a solid ice structure. C. Given that water's freezing pt is 0C and the fp depression constant is 1.86 Ckg/mol, calculate the fp depression for a 3.55 molal soln (moles/kg) of NaCl in water. Assume ideal behavior of the ions. D. Given that water's fp is 0C and fp depression constant is 1.86 Ckg/mol, calculate the fp depression for 3.55 molal solution for CaCl2 in water. Assume ideal behavior of the ions.

The dissolution of solute into a solvent can be dependent on a variety of factors. These include the pH, the ionic strength (amount of salt dissolved), temperature, etc. Other ways to discuss solutions are turbidity, purity, clarity. Pick one of the these factors and discuss.

Can you please show me how to look at this data to answer a through. D    number 64

Why is it important that we have defined the system as the dissolved ions and their respective solvation shells?
