Using Dimensional AnalysisAnalyzing Reactions RxNExplanation:

Step 1: Define

[RxN - Balanced] 2K + Br₂ → 2KBr

[Given] 1.67 moles K

[Solve] moles KBr

Step 2: Identify Conversions

[RxN] 2 mol K → 2 mol KBr

Step 3: Stoichiometry

[DA] Set up conversion:                                                                                 [DA] Multiply/Divide [Cancel out units]:
