Step 1: Define

[RxN] 2Na + Cl₂ → 2NaCl

[Given] 34.485 g Na

Step 2: Identify Conversions

[RxN] 2 mol Na = 1 mol Cl₂

Molar Mass of Na - 22.99 g/mol

Step 3: Stoichiometry

Step 4: Check

Follow sig fig rules and round. We are given 5 sig figs.

Since our final answer has 2 sig figs, there is no need to round.

they are both synthetic elements
