which of the following ways?
a) Mass per cent or weight per cent ( w/w%)
b) Mole fraction or molarity
c) Molality d) All of the above

Answer 1

Answer:

because the consent ration of the solution taking all valume

Answer 2

Option C) Molality

The concentration of a solution or the amount of substance present in its given volume can be expressed in Molality ways.

• The moles of the solute present per kilogramme of the solvent, or "molality," is measured. The concentration of a solution is expressed as a mass percentage. This is how it is explained: A component's mass percentage in a solution is determined by how many grammes of that component there are in every 100 grammes of the solution.
• The quantity of a material dissolved in a given mass of solvent is known as its molality (m), also known as molal concentration. The moles of a solute per kilogramme of a solvent are how it is defined.
• The number of moles of solute contained in 1000 g of the solvent is known as molality. One molal of NaOH, for instance, is one mole of NaOH in one kilogramme of water. The formula for molality(m) is number.
• A chemical solution's concentration can be expressed using both molality (m) and molarity (M). The moles of solute per kilogramme of solvent is measured by molality. The moles of solute per litre of solution is measured as molarity.
