number of moles=solute concentration/solute molar mass
The answer is 0,16 moles.
This is the molar concentration of the solute.
molarity = number of moles of solute / volume of solution number of moles of solute = molarity x volume of solution number of moles of solute = 12 (mole/L) x 15/1000 (L) number of moles of solute = 0.18 mole
The number of moles of solute will not change. Too, the molarity of the solution decreases.
The concentration in moles of a substance in the solution
This is the molar fraction.
The number of moles of a solute per kilogram of solvent. (Apex)
The difference is in the denominators.Molarity (M) - the number of moles of solute divided by the number of liters of solution.Molality(m) - the number of moles of solute divided by the number of kilograms of solvent.
The number of moles of solute dissolved in 1 L of a solution would be the molarity. As an example, if you had 2 moles of solute in 1 liter the molarity would be 2M.
1 mole in 250 ml and 4 moles in 1 liter or 1000 mls
The molarity is a form of expression for the concentration; the molarity of a solution is the number of moles of solute in the solvent. The number of moles is the ratio between the mass of the solute in the solution and and its molar mass.
Mole is the molecular weight of a compound in grams.Mass is the mass of the solute dissolved in the solution.Molar concentration is the number of moles of the solute in the unit of volume of the solution.Volume is expressed in a unit of SI.
