Answer:
The solution that is least concentrated is the one containing 4 moles of solute dissolved in 6 liters of solution .
Explanation:
Concentration is defined as the amount of a substance in a given apquantitybof solvent or solution. The unit of concentration is usually given as mol/litre
Mathematically, concentration = Number of moles of solute/ volume of solution in litres.
To determine the solution that is least concentrated from the given solutions, their concentrations in mol/L is calculated.
Concentration of solution containing 4 moles of solute dissolved in 6 liters of solution = 4 mol/6 litres = 0.67 mol/L
Concentration of solution containing 1 mole of solute dissolved in 1 litre of solution = 1 mol/ 1 litre = 1 mol/L
Concentration of solution containing 1 mole of solute dissolved in 1 liter of solution = 1 mol/ 1 litre = 1 mol/L
Concentration of solution containing 8 moles of solute dissolved in 4 liters of solution = 8 moles / 4 litres = 2 mol/L
Concentration of solution containing 8 moles of solute dissolved in 4 liters of solution = 8 moles/ 4 litres = 2 mol/L
Concentration of solution containing 3 moles of solute dissolved in 2 liters of solution = 3 moles / 2 litres = 1.5 mol/L
Therefore, the solution that is least concentrated is the one containing 4 moles of solute dissolved in 6 liters of solution .
