A solution is prepared by dissolving 0.330 mol of sodium chloride (NaCl, 58.44 g/mol) in 0.2500 kg of water.How many grams of the solution contain 0.133 mol of NaCl?

Question

Quizplus · Accepted Answer

First, calculate the mass of NaCl: 0.330 mol * 58.44 g/mol = 19.2852 g. The mass of the solution is the mass of NaCl plus the mass of water: 19.2852 g + 250 g = 269.2852 g. To find how many grams of the solution contain 0.133 mol of NaCl, use the ratio: (0.133 mol / 0.330 mol) * 269.2852 g = 109 g.
