Answer: 642.93 g of NaCl
Step-by-step explanation:
11.00 mol NaCl x __58.448 g__ = 642.928 g of NaCl
1 mol NaCl
I would round to 642.93 g of NaCl, but round to however many significant figures asked for.
My chemistry teacher made this map (image attached) to teach us how to do conversions. Just follow the map. I think it's pretty straight forward. I hope this helps.
