Answer:
590 g CaCl₂
General Formulas and Concepts:
Chemistry - Atomic Structure
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
Step 1: Define
5.3 mol CaCl₂
Step 2: Identify Conversions
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
[tex]5.3 \ mol \ CaCl_2(\frac{110.98 \ g \ CaCl_2}{1 \ mol \ CaCl_2} )[/tex] = 588.194 g CaCl₂
Step 4: Check
We are given 2 sig figs. Follow sig fig rules and round.
588.194 g CaCl₂ ≈ 590 g CaCl₂
