Na + Cl₂ ⇒ NaCl 1. Check for a balanced chemical equation. . 2. Check for STP. If it's not balanced, balance it. This is important for mole ratio if you'll need it. R = gas constant 8.31 L kPa/mole * K 0.0821 L* atm/mole * K 3. Are you given liters or grams? PV = nRT If there's not STP (0 C, 1 atm), you'll need to use Ideal Gas Law to find "V" or "n". . If you're given liters, change to moles using the Ideal Gas Law. Once you have moles, you can use mole ratio and molar mass stoichiometry to determine a mass for the product. If you're given grams, change to moles using molar mass and apply a mole ratio to determine "n" for the other chemical. Once you have "n" for the other chemical, you can use the Ideal Gas Law to solve for "V"."
