Question

3.3x10^34 convert molecules to moles

Answer 1

5.5 × 10¹⁰ moles

General Formulas and Concepts:

Chemistry - Atomic Structure

• Using Dimensional Analysis
• Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

Step-by-step explanation:

Step 1: Define

3.3 × 10³⁴ molecules

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

`3.3 \cdot 10^(34) \ molecules((1 \ mole)/(6.022 \cdot 10^(23) \ molecules) )` = 5.47991 × 10¹⁰ moles

Step 4: Check

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

5.47991 × 10¹⁰ moles ≈ 5.5 × 10¹⁰ moles
