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 :)
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
What is the most appropriate to express number of molecules per volume?
Avogadro's number is the number of molecules in a mole of a substance. This is expressed as 6.022 141 29 E23 /mol. This is defined as the number of atoms in 12 grams of carbon12. A mole of any gas has this number of molecules. Any fraction of that mole must be divided into the number.
1Molar 1 ml solution convert in to millimole?
You have 1ml. Molar means 1 mole per litre. So if you have 1 mole in a litre, you have 0.001 moles in 0.001 litres. 0.001 moles is 1 millimole.
What is the mole ratio of potassium chloride?
1:1, one mole potassium to one mole chlorine
