Question

a molal solution is one that contains 0.5 mole of solute in:

Answer 1

Answer:

Molality is the number of moles of solute dissolved in 1000 grams of solvent. So 1 molalal solution contains one mole of solute in 1000 grams of solvent. 1M=1liter1mole.

Answer 2

In molality determination, 0.5 moles of a solute will be contianed in 1000 grams / 1 kilogram of solvent.

Explanation:

• The molality is defined as the number of moles of a solute present per kgs of a solvent. It is represented as "m" and its unit is mol/kg.
• Its formula is : number of moles of solute/mass of solvent in kilograms.
• The 0.5 moles of a solute will be present in 1000 grams/1 kilogram of solvent to make it a molal solution.
• Its molality will be 0.5 / 1 = 0.5 m.
