Dilution and Molarity**Problem:**What is the final molarity that would result if you diluted 180.0 mL of a 1.55 M HCl solution to a final volume of 500.0 mL?**Solution Approach:**Use the dilution formula: \[ M_1V_1 = M_2V_2 \]Where:- \( M_1 \) = initial molarity- \( V_1 \) = initial volume- \( M_2 \) = final molarity- \( V_2 \) = final volume#### 7. Reaction Stoichiometry**Problem:**Determine the volume of 1.5 M KI solution required for the reaction of 10.00 grams of lead(II) nitrate.**Reaction:**\[ \text{Pb(NO}_3\text{)}_2 + 2\text{KI} \rightarrow \text{PbI}_2 + 2\text{KNO}_3 \]**Solution Approach:**1. Calculate moles of lead(II) nitrate using its molar mass.2. Use the stoichiometry of the balanced equation to find moles of KI needed.3. Use molarity (\( M = \text{moles/volume} \)) to find the required volume of KI solution.#### 8. Mass from Molarity**Problem:**How many grams of KNO\(_3\) are contained in 245 mL of 3.00 M KNO\(_3\) solution?**Solution Approach:**1. Convert volume to liters.2. Use molarity to find moles of KNO\(_3\).3. Calculate mass using the molar mass of KNO\(_3\).#### 9. Percent Yield**Problem:**If the combustion of 4.00 grams of magnesium results in the actual yield of 5.00 grams of magnesium oxide, what is the percent yield of the reaction?**Reaction:**\[ 2\text{Mg(s)} + \text{O}_2\text{(g)} \rightarrow 2\text{MgO(s)} \]**Solution Approach:**1. Calculate the theoretical yield of MgO using stoichiometry based on starting mass of magnesium.2. Use the formula for

AHMAD, ASHNA 5 of 35 1 4. 6. 7 A student has two rubber balls of different masses to perform an experiment. Which experiment can the student do to objects? O Roll the rubber balls on thick carpet, and observe if either ball produces a spark. O Move a magnet near each rubber ball, and observe if either ball is attracted to the magnet. O Place the rubber balls ona rough surface, apply a small push, and record the time for each ball to move 30 cm. O Drop the rubber balls at the same time from 5 m, and record the time for each ball to hit the ground. P Type here to search 5.
