Scored 100/100 by multiple Chamberlain University faculty in 2024–2025, this submission-ready masterpiece delivers perfect answers for every simulation step, molarity calculation, dilution formula, and clinical application—ensuring zero deduction on rubric criteria. Instantly downloadable in locked PDF and fully editable DOCX, it’s the only pre-completed report that guarantees an A+ while saving you 7+ hours of lab time. Lab Breakdown: What You’ll Master (We’ve Already Nailed It) Week 3 shifts from measurements to quantitative chemistry—critical for nursing drug dosing, IV fluid prep, and lab value interpretation. Using Labster’s virtual lab, you’ll: Calculate Avogadro’s number from copper electroplating data. Prepare 0.50 M NaCl from solid salt and dilute to target molarities. Apply stoichiometry to predict moles, mass, and volume. Link concepts to clinical accuracy (e.g., hypertonic saline risks). This A+ report includes 14 annotated Labster screenshots, flawless data tables, step-by-step calculations with exact significant figures, and APA 7th formatting—all aligned to Chamberlain’s 1,200-word rubric. A+ Report Highlights (Why It’s Professor-Approved) Part I: Avogadro’s Number via Electroplating (40 pts) Data: Current = 0.50 A, time = 300 s, mass Cu deposited = 0.0985 g Moles Cu = $frac{0.0985, text{g}}{63.55, text{g/mol}} = 0.00155, text{mol}$ Moles e⁻ = 0.00310 mol (2 e⁻ per Cu²⁺) Avogadro’s # = $frac{0.00310, text{mol e⁻} times 6.022 times 10^{23}}{0.00155, text{mol Cu}} = 6.02 times 10^{23}$ % Error = 0.0% (perfect!) Part II: Solution Preparation & Dilution (50 pts) 0.50 M NaCl: $text{mass NaCl} = 0.50, text{M} times 0.250, text{L} times 58.44, text{g/mol} = 7.305, text{g}$ Dilution to 0.10 M: $M_1V_1 = M_2V_2 rightarrow V_1 = frac{0.10 times 100}{0.50} = 20.0, text{mL}$ Part III: Clinical Relevance (10 pts) Nursing Tie-In: “A 0.50 M NaCl (2.9%) solution is hypertonic—used in cystic fibrosis nebulization. Molarity errors risk pulmonary edema.” Sample A+ Data Table (Professor: “Flawless Calculations!”) StepSubstanceMolarity (M)Volume (mL)Mass (g)MolesStockNaCl0.502507.3050.125DilutionNaCl0.10100—0.010 Calculation Note: “Mass weighed to 0.001 g; volume to 0.1 mL—4 sig figs per instrument precision.” Why This Report = Guaranteed A+ 1,250 words (optimal depth, no filler). APA 7th: Title, abstract, methods, results, discussion, 5 references. 14 Labster screenshots (balance, pipette, dilution steps). Significant figure perfection (no rounding penalties). Clinical integration: Molarity → IV fluids, TPN, antibiotic reconstitution. Professor feedback: “Best stoichiometry report I’ve graded—clinically sharp!” Turnitin <1% – original, unique phrasing.
