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
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.
How many grams of chlorine are required to react completely with 5.00 grams of sodium to produce sodium chloride ? 2na + cl2 → 2nacl
