Answer:
0.717m
Explanation:
Molality, m, is an unit of concentration defined as the ratio between moles of solute and kg of solvent:
Molality: Moles solute / kg solvent.
In the problem, water is the solvent (Is the compound in the higher quantity) whereas H₂SO₄ is the solute.
The concentration of the solution is 0.750 moles H₂SO₄ / L.
Thus, you need to convert the liters to kg to obtain the molality. That is:
0.750 moles H₂SO₄ / L ₓ (1L / 1000mL) ₓ (1mL / 1.046g) ₓ (1000g / 1kg) =
0.717 moles H₂SO₄ / kg
0.717 m
