Edexcel IAL Chemistry A2 6.P8 process and analyse practical data
The direct questions move from graph readings to calculation chains: use absorbance or practical data, apply dilution or density steps and report the requested unit.
How this is tested
- Read concentration from absorbance data and report ppm or mol dm^-3 as required.
- Scale a diluted copper(II) sulfate result back to the original concentration.
- Combine percentage by volume, density and mass data to calculate moles of glycerol.
