Problem- 25.00g of a salt with molar mass 175.00g/mol is dissolved in 385g of acetic acid. The boiling point of the solution is 119.5oC. The boiling point of pure acetic acid is 118.1oC and kb (acetic acid)=3.07oC/m. What is the vant Hoff factor(i) of the salt?
Please show me how work it out above problem

Three solutions are mixed together to form a single solution. One contains 0.2 mol Pb(CH3COO)2, the second contains 0.1 mol Na2S, and the third contains 0.1 mol CaCl2. Write the net ionic equations for the precipitation reaction or reactions that ..
Think back to what you learned in this course about solutions and intermolecular forces. Why don't these to "mix" together (in other words, make a homogenous solution) when combined. Why do they separate into layers
