⚙️ The 6-Step Calculation Method (Works Every Time!)
- WRITE the balanced equation — you can't do anything without this!
- IDENTIFY what you know (given in question) and what you need to find
- CALCULATE moles of the known substance using n = m ÷ Mr
- USE THE RATIO from the balanced equation to find moles of the unknown substance
- CONVERT back to the units asked for (mass, volume, concentration, etc.)
- CHECK — does your answer make sense? Is it a reasonable size?
