A particle diagram is a symbolic representation of atoms and molecules at the microscopic level. Whi the following particle diagrams represents the following stage of the Pbl procedure: • In the casserole dish after the evaporative collection

(1) (2) ] A certain species of trout requires dissolved oxygen of 7.5 mg/L. Would it be wise to release the trout in a mountain stream at an altitude with a Po2 = 0.17 atm. (KH (02) = 1.3x10-³ mol/Latm). Calculate the mole fraction for the following: 14.5 g of HNO3 in 150 g of H₂O. (b) moles of Solute kg Solvent X (a) H=1.01 N = 14.00- 50 mm= 63.01 g/mol 03=16.0x3 Imol 14.6g HNO3 63.01g 149 150 g 1000g = 0.15 kg 6.00 M HCI. (notice, concentration is an extensive property. You can assume any volume!) 0.23 mol HNO3 0.16 kg H2O 1.53 = 0.23 mol HNO3

You are asked to prepare a 1.000 L solution of 4.5 M you commit a user error while preparing this solution. Assumed volume Volumetric error Preparation details Added water 2.0 cm above the line, which corresponds to 8.2 mL (0.0082 L) additional solution volume C6H12O6 (glucose; molar mass = 180.16 g/mol) in a lab by dissolving 811.0 g of glucose in water. Consider the following two scenarios in whic Prepared in a beaker Prepared in a volumetric flask 1.000 L You add the glucose to a volumetric flask and then add water until it dissolves. The water bottle you are using has a worn tip, and you inadvertently add too much water such that the meniscus is above the line. The diameter of the neck of the volumetric flask is 2.29 cm. 811.0 g glucose Concentration: You decide to evaluate and compare the errors you made while preparing the solutions using the different methods. Calculate the actual concentrations of the intended 4.5 M glucose solutions prepared by each method based on their…

7.0 mL of 3.0 M NaOH are diluted with water to a volume of 400 mL. (a) Determine the molarity of the resulting solution. How many moles of NaOH there are in 7.0 mL of 3.0 M NaOH?  Hint: Use Eq. 1 and make sure the volume is in liters: MA = mol A / soln (L) OR mol A = MA x V ___________ moles (b) The total number of moles of NaOH is not changed on dilution.  The molarity after dilution can therefore be found by  MA = mol A / soln (L) OR mol A = MA x V using the final volume of the solution.  Calculate that molarity.
