A grandma here trying to work with 10th grader on chemistry and have been given absolutely no info from teacher (we are virtual) to even know what to do.
So Here is a example of a chemical recipe:
2NA + Cl2 yields 2 NaCl
If you have 2 moles of NaCl, how many moles of sodium do you have.
I would say 2 but not sure and can't explain why
