Particles from moles
A sample in a battery electrolyte lesson contains \(0.14\,\text{mol}\). Using \(N_A=6.02\times10^{23}\,\text{mol}^{-1}\), calculate the number of particles in units of \(10^{23}\). Enter the answer and choose the interpretation that matches the chemistry.
Worked practice: chemistry evidence and answer
Use the chemical evidence first, then enter the result and interpretation that match it.
Write a full answer
Now write the response in full, in your own words — this is what the exam asks for. The AI marks it on the same moves you built above (focus, evidence, technique, judgement) and gives feedback on reasoning, evidence, and expression.
