Work it, then mark it
Do each calculation on paper first, then reveal the mark scheme and tick the marks you actually earned — the same way you should mark past papers.
Q1
Do the calculation on paper first — then mark it.
Where the marks get lost
- Using 24 000 and then converting to cm3 again.
- Applying the 24 dm3 value when conditions are not RTP.
Exam tip: Choose either 24 dm3/mol or 24 000 cm3/mol to match the requested unit.
