solution of potassium chloride. The concentration of a solution equals the mass A chemistry student must write down in her lab notebook the concentration of of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 3.250 g • She put some solid potassium chloride into the graduated cylinder and weighed it. With the potassium chloride added, the cylinder weighed 29.91 g. ....
