To prepare a solution with a concentration of 2.18 grams of salt in 250 milliliters of water, the ratio of salt to water is 2.18:250. With 4.5 grams of salt, the amount of solution produced can be calculated using the proportion 2.18/250 = 4.5/x, solving for x gives x = (4.5 * 250) / 2.18 = 516.055 milliliters.
