Paper 1, Paper 2 5 marks Difficulty 3

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.
