Using Dimensional AnalysisAnalyzing reactions RxNExplanation:

Step 1: Define

[RxN - Balanced] 6H₂ + O₂ → 3H₂O

[Given] 18 mol H₂

[Solve] mol H₂O

Step 2: Identify Conversions

[RxN] 6 mol H₂ → 3 mol H₂O

Step 3: Stoich

[DA] Set up conversion:                                                                               [DA] Simplify:                                                                                                 [DA] Divide [Cancel out units]:                                                                    

m=9

step-by-step explanation:

7m+8=71 subtract   8 from 71 which is 63 than divide it by 7m   equal 9.
