What volume of chlorine gas at 34.0◦C and

1.38 atm is needed to react completely with
9.40 g of sodium to form NaCl?
Answer in units of L.

1 answer

2Na + Cl2 ==> 2NaCl

mols Na = grams/atomic mass = ?
Using the coefficients in the balanced equation, convert mols Na to mols Cl2.
Then use PV = nRT to convert mols Cl2 to volume at the conditions listed.
