Does the mole of solution is equal to mole of solute plus mole of solution?
No, the mole of solution is not equal to the mole of solute plus the mole of solvent. The mole of solution refers to the total amount of moles in a given volume of solution, which includes both the solute and the solvent.
What is the mole fraction of solute in 3.52m aqueous solution?
To find the mole fraction of solute in a 3.52 m (molal) aqueous solution, we first need to determine the moles of solute and the moles of solvent (water). A 3.52 m solution means there are 3.52 moles of solute per 1 kg of water. The molar mass of water is approximately 18.015 g/mol, which corresponds to about 55.5 moles of water in 1 kg. The mole fraction of solute (X_solute) can be calculated using the formula: [X_{\text{solute}} = \frac{\text{moles of solute}}{\text{moles of solute} + \text{moles of solvent}} = \frac{3.52}{3.52 + 55.5} \approx 0.059. ] Thus, the mole fraction of solute is approximately 0.059.
Why doesn't adding one mole of solute to one liter of water make a one molarity solution?
Because molarity is a measure of the concentration of a solute in a solution, defined as the number of moles of solute per liter of solution. If you add one mole of solute to one liter of water, you have a total volume of one liter but only one mole of solute, so the molarity would be 1 mole/L, not 1 M.
What are the molality and mole fraction of solute in a 25.5 percent by mass aqueous solution of formic acid (HCOOH)?
The molality is 5,54.
