VS. Use a second thermometer/temperature probe to check the temperature. 6. Use a 100 ml. graduated cylinder to measure 50.0 mL of hot water y Record the temperature of the "hot" water in your lab notebook. 0 Mix the hot water with the cold water in the calorimeter replacing the lid quickly, and the record the temperature of the combined solution every 15 seconds for six minutes (24 readings). Note:...

Please I need help with number 54 and 61 please
An aqueous NaCl solution is made using 112 g of NaCl diluted to a total solution volume of 1.00 L. Calculate the molarity, molality, and mass percent of the solution. (Assume a density of 1 08 g/mL for the solution.) An aqueous KNO_3 solution is made using 72.5 g of KNO_3 diluted to a total solution volume of 2.00 L. Calculate the molarity, molality, and mass percent of the solution....

6 pts Question 2 A student designs an experiment to test the hypothesis: "If a solution of sucrose in water has a higher concentration, it will attract more ants." The student makes sucrose solutions with concentrations of 1.00,5.00, 10.50, 20.00 and 25.00% sucrose by mass, then leaves the solutions outside. After some time has passed, the student counts the number of ants that are in each beaker. The independent variable for this experiment is the:...
