Which of the following statements is (are) incorrect? (Choose all that apply) It is important to get exactly 5.000g of salt when preparing the 5% solution. It is important to measure the mass of water added to solution accurately and precisely. It is important to measure the mass of solution accurately and precisely. For the calibration curve, density is plotted on the x-axis, %NaCl is plotted on the y-axis. The density of the unknown salt solution needs to be remeasured this week. Salt is more dense than water. It is important to measure the volume of water added to solution accurately and precisely. It is important to measure the volume of total solution accurately and precisely. When constructing the calibration curve, use the actual %NaCl for each standard solution
