a chemist performs the sunthesis of sodium chloride from its elements. The chemist begins with 46 grams of sodium. How many grams of sodium chloride are produced? 2Na + Cl2 --> 2NaCl

• chemistry -

46 g Na is how many moles?
46/23 = 2 moles Na.

Looking at the equation, 2 moles Na will produce 2 moles NaCl.

How many grams is that?
moles x molar mass = grams.
