Hello, I hope you are doing well on this fine day. For the following quetion please read carefully the question and instruction. PLEASE ANSWER QUESTION IN 20 MINTUES NOT MORE PLEASE AND THANK YOU. If you do answer the question correctly and post it in the next 20 minutes, NO NEED TO SHOW ALL THE WORK, I JUST WOULD LIKE THE CORRECT ANSWER AS SOON AS POSSIBLE. I will write a wonderful and generous feedback/review/rating about you. NOT ONE HOUR!!! THIS IS A TEXTBOOK QUESTION HURRRY UP PLEASE You perform the conductivity experiment as described in the lab manual using NaCl solutions of known concentrations. You plot the conductivity of your solutions (μS/m) as a function of the concentration (mol/L). You make a trendline with an equation of y = 1.42 x 105 x + 9.94 x 102. You then test the conductivity of an unknown sample of chicken broth. If the chicken broth conductivity is 7.12 x 103 μS/m.  What is the concentration of NaCl in the broth in mol/L?

Soil Lab 11a Direct Measurement of Soil Porosity 1. Fill a 100 ml graduated cylinder to the 100 ml mark with tap water. Tilt the beaker containing the soil sąved from Step 3 in the Bulk Density Determination to about a 45 degree angle. Pour the water very slowly onto the soil in the beaker. Stop adding water when the soil pores are filled (saturated) and the soil surface glistens. 2. Allow the soil to stand for several minutes to make sure the water has filled the very small soil pores. Any excess water can be returned to the graduated cylinder. Don't stir or shake the mixture. 3. Determine the amouht of water used to exactly fill the pote space in the 100 cubic cehtimeters of soil. Subtrąct the reading of water level on the side of the graduated cylinder from the original volume of 100 ml. Note that the water which was poured onto the soil exactly filled the pore space and thus equals the total pore volume by direct measurement. 4. Record your results below and make the necessary…

This assignment is designed to help you learn how to determine total costs by combining direct and indirect costs for a particular department. In this GHA, you will be determining the total costs for three departments: (1) Physical Therapy (2) Occupational Therapy and (3) Speech Therapy. To determine the total costs, you will need to add the direct costs to the indirect costs using the template provided below. Please use the example provided in the assignment description if you find that you need some support understanding the required calculations. DIRECT COSTS The direct costs for each department are easily identifiable, because they are the costs that are directly attributable to the department. The direct costs are as follows: Physical Therapy (PT) Occupational Therapy (OT) Speech Therapy (ST) Total Direct Costs INDIRECT COSTS The indirect costs will need to be allocated to Physical Therapy (PT), Occupational Therapy (OT), and Speech Therapy (ST). The indirect costs in this…
