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

Question

A. quantitative relationship: (chemistry only) (HT only) Substitute numerical values into algebraic equations using appropriate units. (MS 3c)
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) Substitute numerical values into algebraic equations using appropriate units. (MS 3c).

Explanation

The correct option is quantitative relationship: (chemistry only) (HT only) Substitute numerical values into algebraic equations using appropriate units. (MS 3c). It is correct because it directly supports the approved learning objective to (chemistry only) (HT only) Substitute numerical values into algebraic equations using appropriate units. (MS 3c). 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

Incorrect Unit Conversion

Students often forget to convert volumes from cm3 to dm3 when substituting into concentration equations.

Always convert cm3 to dm3 by dividing by 1000 before using the volume in calculations.
