Exam-style question
Try this first
Case 26 unit-check. A student checks the units in a calculation. Which decision keeps the method valid? Focus on Substitute numerical into algebraic equations units in Concentrations in mol/dm3 and titration calculations, not on a neighbouring Unit 4.3 idea.
- A.Case 26 unit-check: Keep the required unit linked to the quantity being calculated for Substitute numerical into algebraic equations units
- B.Case 26 unit-check: Ignore the unit because the number is more important (Concentrations in mol/dm3 and titration calculations)
- C.Case 26 unit-check: Swap dm3 and cm3 without converting the value (Substitute numerical into algebraic equations units)
- D.Case 26 unit-check: Use grams, moles, and percentage signs interchangeably (Using concentrations of solutions in mol/dm3 (chemistry only) (HT only))
