In one molal solution that contains 0.5 mole of a solute, there isa)5...
Explanation:
One molal solution contains 1 mole of solute dissolved in 1000g (or 1kg) of solvent. In this case, the solution contains 0.5 mole of solute. Therefore, we need to calculate the amount of solvent in the solution.
Calculation:
Given that the solution contains 0.5 mole of solute.
Formula:
Molality (m) = (moles of solute) / (mass of solvent in kg)
Substitute the values:
1 mol/kg = 0.5 moles / x kg
Solve for x:
x = 0.5 / 1 = 0.5 kg = 500g
Therefore, in the given one molal solution containing 0.5 mole of solute, there is 500g of solvent.
