  sodium chloride can be reproduced from the reaction between sodium metal and chlorine gas.

a. how much table salt will be formed if 5.41 of sodium reacts?
b. how much chlorine is required?


please help me as soon as possible.

OK, now, can you convert your units of mass of Na (5.41 g) to the units given in Janhaa:'equation, which is moles?  You'll be able to determine moles of product, and you'll have to convert moles to grams, again.  The same applies to the Cl2 (pay attention, diatomic gas).  Let's see you try to work through it.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
