Could you please help me figure out how to prepare a 1M solution of
NaCl. And how to prepare a 120mM solution from the IM stock. Thank you.

You Should be able to do the dilution calculation on your own, but if
you want a double check, google "dilution calculator" - its one of
those things you discover when you're making solutions at 4 am half
dead/asleep

Cheers,
Jen
