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.
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.
What does molarity M measure in a solution?
Concentration
How do you convert mole fraction to volume fraction of liquid?
You need the balanced symbol equation for the reaction. The numbers in front of the formulae show the mole ratios. For example, in the thermal decomposition of calcium carbonate: CaCO3 --> CaO + CO2 The equation is balanced. The mole ratio between CaCO3 and CO2 is 1:1 because there is 1 mole of CaCO3 for every mole of CO2
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 a 3.82 m aqueous solution?
To find the mole fraction of solute, you need to know the moles of solute and solvent. In this case, the moles of solute can be calculated by multiplying the molarity of the solution by the volume of the solution. Once you have the moles of solute and solvent, you can find the mole fraction of solute by dividing the moles of solute by the total moles of solute and solvent.
What is the mole fraction of solute in a 3.62 m aqueous solution?
To find the mole fraction of solute in a solution, you need to know the total moles of both the solute and the solvent. In this case, the moles of the solute is 3.62 mol and the moles of the solvent (water) is not given. Without the moles of the solvent, the mole fraction of the solute cannot be calculated.
What is the mole fraction of solute in a 3.30 m aqueous solution?
To find the mole fraction of solute, we need to know the moles of solute and moles of solvent. Here, the concentration (3.30 m) tells us the moles of solute per liter of solution, but we need more information to calculate the mole fraction. We would need the moles of solute and moles of solvent to proceed.
What is the mole fraction of solute in a 3.71 m aqueous solution?
To find the mole fraction of solute in a solution, you need to know the moles of solute and solvent. In this case, the concentration is given in molality (3.71 m), which means there are 3.71 moles of solute per kilogram of solvent. Without knowing the identity of the solute, the mole fraction cannot be calculated.
What is the mole fraction of solute in a 3.72 m aqueous solution?
To find the mole fraction of solute in a solution, you need both the moles of solute and the total moles of solute and solvent combined. In this case, the molarity of the solution (3.72 mol/L) is not enough information to determine the mole fraction without knowing the specific solute and its moles.
What is the mole fraction of solute in a 3.12 m aqueous solution?
To find the mole fraction of solute, we need to first determine the moles of solute and solvent. In a 3.12 molal solution, there are 3.12 moles of solute in 1 kg of solvent. Using the density of water (1 g/mL), we can convert the 1 kg of solvent to 1000 g. Knowing the molar mass of water (18 g/mol), we can convert 1000 g to moles. Finally, the mole fraction of solute is the moles of solute divided by the total moles of solute and solvent.
How do you find the mass percent mole fraction molality and molarity of a solution?
Mass percent = grams of solute/total grams of solution Mole fraction = mols component/total mols mix. Molarity = mols solute/L solution Molality = mols solute/kg solvent Hope this helps :)
When can volume fraction be equal to mole fraction?
The volume fraction of a substance is equal to the mole fraction for ideal gas mixture
What is the mole fraction of methanol in a solution that contains 6.0 mol of methanol and 3.0 mol of water?
The total moles of solute and solvent in the solution is 9.0 mol. The mole fraction of methanol would be the moles of methanol divided by the total moles. Therefore, the mole fraction of methanol in the solution is 6.0 mol / 9.0 mol = 0.67.
What is the mole fraction of HCl in an aqueous solution that is 27.2 percent HCl by weight?
To find the mole fraction of HCl in the solution, we first need to calculate the molar mass of HCl (H=1g/mol, Cl=35.5g/mol). Then, determine the number of moles of HCl in 100g of the solution. Finally, calculate the mole fraction of HCl by dividing the moles of HCl by the total moles of solute and solvent in the solution.
What is the mole fraction of each component if 3.9g of benzene is dissolved in 4.6g of toluene?
The molar mass of benzene (C6H6) is about 78 g/mol and toluene (C7H8) is about 92 g/mol. Calculate the number of moles of benzene and toluene in the solution using the given masses. Calculate the total number of moles in the solution (benzene + toluene) and then determine the mole fraction of each component by dividing the number of moles of each component by the total moles.
