Question
Gas Stoichiometry Soenario #3
What mass (in grams) of sodium chloride (NaCl) will be produced when enough sodium (Na) is
combined with 2.4 L of chlorine gas (Cl₂) at 25 C and 1.2 atm?
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"."
