Using concentrations of solutions in mol/dm3 (chemistry only) (HT only)

Question

A. quantitative relationship: (chemistry only) (HT only) Use ratios, fractions and percentages in titration calculations. (MS 1c)
B. wrong formula: uses a different Unit 4.3 relationship from Concentrations in mol/dm3 and titration calculations
C. wrong unit: gives a value without checking the required unit
D. wrong reasoning: confuses coefficients, subscripts, mass, moles, or concentration

Answer

The correct option is quantitative relationship: (chemistry only) (HT only) Use ratios, fractions and percentages in titration calculations. (MS 1c).

Explanation

The correct option is quantitative relationship: (chemistry only) (HT only) Use ratios, fractions and percentages in titration calculations. (MS 1c). It is correct because it directly supports the approved learning objective to (chemistry only) (HT only) Use ratios, fractions and percentages in titration calculations. (MS 1c). This belongs to Concentrations in mol/dm3 and titration calculations within Using concentrations of solutions in mol/dm3 (chemistry only) (HT only), so the answer must use the named Unit 4.3 relationship and avoid mixing it with nearby ideas such as mass, moles, concentration, yield, atom economy, gas volume, coefficients, or subscripts.

Common mistake

Misunderstanding Ratios in Titration Calculations

Students often confuse the ratios of reactants in titration calculations, leading to incorrect concentration results.

To fix this, carefully identify the coefficients from the balanced equation and apply them correctly to the mole ratios when calculating concentrations.
