Walkthrough

Corrections to numeric calculations in chemistry educational content. Three explicit calculations for FeO mole amounts are adjusted from 0.00166 mol to 0.000166 mol, with corresponding updates to resulting mass values (0.119 g to 0.0119 g) and intermediate calculations.

Title check ❓ Inconclusive The title 'Undirbuningurefnfix' is vague and doesn't clearly convey what changes were made; it appears to be a branch name rather than a descriptive pull request title. Consider using a more descriptive title like 'Fix molar calculations in Chapter 2' or 'Correct FeO molar mass calculations' to clearly indicate the nature of the corrections being made.

⚠️ Potential issue | 🔴 Critical

Excellent correction to the mole calculation!

The updated value of 0.000166 mol is mathematically correct. The calculation (100 × 10^18) / (6.022 × 10^23) = 0.000166 mol fixes the tenfold error that was present in the original value. This is a critical fix for educational content, as incorrect calculations could mislead students learning stoichiometry fundamentals.
