Atoms, molecules and moles test
Please do all working in your exercise book so any of your work steps can be checked if you are making mistakes. Don't forget to include units where possible WITHOUT ANY SPACE and make sure your answer is to the correct significant figures. For most answers don't use scientific notation to input your answers so the computer can quickly grade your answer for you unless it requires you to calculate particles. To input these answers set it out like: 6.02x10^23 (no spaces).
