Answer:

200 g NaOH

General Formulas and Concepts:

  • Reading a Periodic Table
  • Dimensional Analysis

Explanation:

Step 1: Define

5.0 mol NaOH

Step 2: Define conversions

Molar Mass of Na - 22.99 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of H - 1.01 g/mol

Molar Mass of NaOH - 22.99 + 16.00 + 1.01 = 40 g/mol

Step 3: Convert using DA

[tex]5.0 \ mol \ NaOH(\frac{40 \ g \ NaOH}{1 \ mol \ NaOH} )[/tex] = 200 g NaOH

Step 4: Check

We are given 2 sig figs. Follow sig fig rules.

We only have 1 sig fig in 200. No need to round.
