2Na + Cl2 ==> 2NaCl
mols Na = grams/atomic mass
mols Cl2 = mols Na x 1/2 (Look at the coefficients in the balanced equation.)
grams Cl2 = mols Cl2 x molar mass Cl2.
How many grams of chlorine are required to react completely with 5.00 grams of sodium to produce sodium chloride ? 2na + cl2 → 2nacl

2Na(s) + Cl2(g)> 2NaCl(s)
Number of moles= mass/molar mass
Number of moles of sodium= 5/23
=0.213 moles
Mole ratio of sodium to chlorine is 2:1
therefore, number of moles of chlorine =1/2×0.213
=0.1065 moles
Mass= number of moles×molar mass
therefore, mass of chlorine= 0.1065×35.5
=3.78075g
