Question

What volume of Cl2 gas, measured at 687torr and 34∘C, is required to form 27g of NaCl?

Answer 1

Cl2(gas) ==> 2NaCl which isn't balanced but the Cl is balanced and that's what the question is about.
mols NaCl = grams/molar mass NaCl
Using the coefficients in the balanced equation above to convert mols NaCl to mols Cl2. Then use PV = nRT and solve for V Cl2 in L.

Answer 2

Thank you
