How many liters of water must be added to 0 point 2 9 1 g of NaCl to create a saltwater solution that has a concentration of 2 point 4 1 g over cap l ? Use g over cap l is equal to grams of solute over liter of solution

Use concentration = grams of solute ÷ liters of solution, so liters = grams ÷ concentration. Calculate 0.291 g ÷ 2.41 g/L ≈ 0.121 L. Thus the solution needs about 0.121 liters, matching choice D, 0.121 liters.
