Interpretation:
The amount of sucrose (in grams) required in the given amount of water to prepare a solution with a vapor pressure less than that of pure water at
Concept introduction:
Raoult’s law describes the relationship between the partial vapor pressure of a solution and the solvent. This law states that the partial pressure of the solvent in the solution
Mole fraction of a component is defined as the ratio of number of moles of that component to the total number of moles of all the components present in the mixture. The relationship between mole fraction

Answer to Problem 58QP
Solution:
Explanation of Solution
Given information:
The amount of water is,
The vapor pressure of pure water is,
The vapor pressure of the solutionis,
Molar mass of water
Molar mass of sucrose
The moles of water can be evaluated as follows:
Therefore, the moles of water are
Now, the mole fraction of water in the solution is calculated by the expression as follows:
Substitute the values of
The moles fraction of water can be rewritten by the expression as follows:
Substitute the values of mole fraction and the number of moles of water in the above equation,
Thus, the number of moles of sucrose is
The amount of sucrose required in the solution is calculated as follows:
Hence, the amount of sucrose (in grams) required in

The chemical equation for the net ionic reaction of NaCl and KCl with silver nitrate, AgNO3, is shown below. Ag+(aq) + Cl(aq) → AgCl(s) The total mass of the NaCl/KCl mixture is 1.299 g. Adding 50.42 mL of 0.381 M solution precipitates out all of the Cl-. What are the masses of NaCl and KCl in the mixture? Atomic masses: g: Mass of NaCl g: Mass of KCL Ag = 107.868 g mol- 1 Cl = 35.453 g mol- 1 K = 39.098 g mol- N = 14.007 g mol−1 Na = 22.99 g mol−1 0 = 15.999 g mol 1 Question Help: ✓ Message instructor Submit Questionarrow_forwardPart 1.

- Identify the missing starting materials/ reagents/ products in the following reactions. Show the stereochemistry clearly in the structures, if any. If there is a major product, draw the structures of the major product with stereochemistry clearly indicated where applicable. Show only the diastereomers (you do not have to draw the pairs of enantiomers). If you believe that multiple products are formed in approximately equal amounts (hence neither is the major product), draw the structures of the products, and show the detailed mechanism of these reactions to justify the formation of the multiple products. If you believe no product is formed, explain why briefly. (6 mark for each, except f and g, which are 10 mark each)arrow_forward3.
