Using ink, hand$-$write a sample of each calculation right before your results summary table. Start with an algebraic equation $($no numbers yet$)$ of how the calculation was done, including names such as $$grams of NaCl$$ rather than variables such as $$x$.$ After the algebraic form, do one sample calculation with numbers and units, showing unit cancellations. Do not show the same type of calculation repeatedly; show one sample for each type of calculation, then summarize results for other trials in a table. If a calculation is based on a chemical reaction equation, write it down. If you use a spreadsheet to do data tabulation and calculations, also show a typical calculation using cell references $($such as D$3=$C$2/$A$1)$ exactly as it
