Does the mole of solution is equal to mole of solute plus mole of solution?
No. The mole of solution is equal to mole of solute plus mole of solvent (solVENT !, not solution)
Why doesn't adding one mole of solute to one liter of water make a one molarity solution?
molarity of moles of solute/liters of solution(not solvent) the volume of the solvent(even if it started at 1 L) would change after adding the solute depending on the molar mass, density, etc of the solute, the molarity would be different
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 equal to mole of solute plus mole of solvent (solVENT !, not 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 78.11 grams per mole. The molar mass of toluene is 92.14 grams per mole. Mole fraction of a solute equals moles of solute divided by the moles of solute plus the moles of solvent. .5 of each is the mole fraction.
What is the mole fraction of solute in a 3.71 m aqueous solution?
molal = m = moles solute/kg solvent. Assuming water as the solvent 1 kg = 1000 g/18g/mole = 55.56 moles H2O. Moles solute = 3.71 moles. Total moles present = 55.56 + 3.71 = 59.27 moles.Mole fraction solute = 3.71/59.27 = 0.0626
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
The concentration unit that corresponds to the mole of solute per kilogram of solvent is?
mol/kg
What is the mole fraction of solute in a 3.62 m aqueous solution?
0.0613 mole fraction = moles solute/(moles solute + moles water) moles water = 1000 g / 18.02 = 55.49 3.62/(55.49 + 3.62)=0.0613
What is the mole fraction of solute in a 3.30 m aqueous solution?
This is the ratio between the molar concentration of this solute and 3,3.
What is state of solute?
solute can be solid, liquid or gas.One should remember that state of solution is determined by state of solvent.Ex- in a mixture of 1 mole Hg and 1 mole metal the solute is Hg and solvent is metal as solution which is an alloy is solid.
What concentration units is measured in mole of solute per kilogram of solvent?
This the molality (this term is now obsolete).
Why mole fraction is independent of temperature?
as we define mole to be mass of the solute divided by molecular mass of the solute so all the solutes are taken in the solid form not in the liquid like we take 1L in molarity,so solids are generally independent of temp thats why both molality and mole fraction are independent of temperature
Why doesn't adding one mole of solute to one liter of water make a one molarity solution?
molarity of moles of solute/liters of solution(not solvent) the volume of the solvent(even if it started at 1 L) would change after adding the solute depending on the molar mass, density, etc of the solute, the molarity would be different
