Question

If a compound formula mass was experimentally determined to be 58, the chemical formula could be?

Answer 1

NaCl

Step-by-step explanation:

If you follow traditional rounding, Na atomic mass is 23 and Cl atomic mass 35, 23 +35 = 58.

I was taught that Cl is one of the elements you round to 35.5, but this works if you’re not in an advanced chem class.

Answer 2

b because that is the one that is logical and the only one that makes sense
