Step 1: Define

312 g CaCl₂ (calcium chloride)

Step 2: Identify Conversions

Avogadro's Number

Molar Mass of Ca - 40.08 g/mol

Molar Mass of Cl - 35.45 g/mol

Molar Mass of CaCl₂ - 40.08 + 2(35.45) = 110.98 g/mol

Step 3: Convert

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

1.69298 × 10²⁴ atoms CaCl₂ ≈ 1.69 × 10²⁴ atoms CaCl₂
