First Principles Assignment 4. Breaking the problem down to its parts and apply logic to set up the solution. In this assignment, we are going to revisit the thermodynamics problems we saw in assignment 2. We are going to go through all the steps we've done so far and add using logic to find the appropriate equation to answer the problem. Again, you do not need to solve the problem, unless you want to. What is required in the assignment is to list your givens, list any questions you have, restate in your own words what the problem is asking for and then use the attached equation list to find the appropriate equation or equations to find the solution. Also, tell me why you should use the equation(s) you choose. See the example provided. Example: The vacuum gage connected to a chamber-reads-5-8-psi-at-a-location where the atmospheric pressure is 14.5 psi. Determine the absolute pressure in the chamber.. Given: The chamber pressure of 14.5.psin ........The atmospheric pressure 5.8 psi No assumptions were given. 1 Question: What is absolute pressure? What does the question ask for:The question is asking me to calculate the absolute pressure in a chamber. Equations:I-can use the equations below because I am looking for the absolute pressure the problem has given-me-chamber pressure and atmospheric pressure. Pabs = Patm - Prac 1. What is the molarity of the solution given that 1.0 moles of potassium fluoride is dissolved to make 0.10 L of solution. 2. Find the pH of a solution that contains 85 grams of hydrochloric acid (HCl) dissolved in 2.5L of water. 1 3.A balloon is filled with 35.0 L of helium in the morning when the temperature is 20.00C.By noon the temperature has risen to 45.00 C. What is the new volume of the balloon? 4. A solution is created by measuring 3.60 x 10 moles of NaOH and 5.95 x 10 moles of HC! into a container and then water is added until the final volume is 1.00 L. What is the pH of this solution? (this may take some though) 5. A manometer is used to measure the pressure in a tank. The fluid-used has a specific gravity of 0.85, and the manometer column height is 55 cm. If the local atmospheric pressure is 96 kPa, determine the absolute pressure within the tank. 1
