Answer:
180 g Ca
General Formulas and Concepts:
Chemistry - Atomic Structure
- Reading a Periodic Table
- Using Dimensional Analysis
Explanation:
Step 1: Define
4.4 mol Ca
Step 2: Identify Conversions
Molar Mass of Ca - 40.08 g/mol
Step 3: Convert
[tex]4.4 \ mol \ Ca(\frac{40.08 \ g \ Ca}{1 \ mol \ Ca} )[/tex] = 176.352 g Ca
Step 4: Check
We are given 2 sig figs. Follow sig fig rules and round.
176.352 g Ca ≈ 180 g Ca
