Question

Calculate the number of moles of each compound, given the number of molecules. If you need to make a number a superscript, put a ^ in front of the number. For example, 2.45 x 1022 would be written as 2.45 x 10^22. 2.46 x 1021 molecules of CO2 10,000 molecules of H2O 8.75 x 1032 molecules of C6H12O6

Answer 1

Answer:

-  4.08×10⁻³ moles of CO₂

-  1.66×10⁻²⁰ moles of H₂O

-  1453.5 moles of C₆H₁₂O₆

Explanation:

Let's determine the amount of molecules of each compound:

- 2.46×10²¹ molecules of CO₂

- 1×10⁴ molecules of H₂O

- 8.75×10³² molecules of C₆H₁₂O₆

1 mol  has 6.02×10²³ moles, so the rule of three will be:

NA of molecules are contained in 1 mol

- 2.46×10²¹ molecules of CO₂ are contained in (2.46×10²¹/ NA) =

- 1×10⁴ molecules of H₂O are contained in (1×10⁴ / NA) =

- 8.75×10³² molecules of C₆H₁₂O₆ are contained in (8.75×10³² / NA) =

-  4.08×10⁻³ moles of CO₂

-  1.66×10⁻²⁰ moles of H₂O

-  1453.5 moles of C₆H₁₂O₆

Answer 2

The number of moles in each compound is:

• 2.46 x 10²¹ molecules CO₂ = 0.00408 mol CO₂
• 10,000 molecules H₂O = 1.66 × 10⁻²⁰ mol H₂O
• 8.75 x 10³² molecules C₆H₁₂O₆ = 1.45 × 10⁹ mol C₆H₁₂O₆

What is Avogadro's number?

It is the number of atoms or molecules in one mole of a substance, equal to 6.023 × 10²³.

We want to convert molecules to moles, so Avogadro's number will be the conversion factor.

• 2.46 x 10²¹ molecules CO₂ × 1 mol CO₂/6.023 × 10²³ molecules = 0.00408 mol CO₂

• 10,000 molecules H₂O × 1 mol H₂O/6.023 × 10²³ molecules = 1.66 × 10⁻²⁰ mol H₂O

• 8.75 x 10³² molecules C₆H₁₂O₆ × 1 mol C₆H₁₂O₆/6.023 × 10²³ molecules = 1.45 × 10⁹ mol C₆H₁₂O₆

The number of moles in each compound is:

• 2.46 x 10²¹ molecules CO₂ = 0.00408 mol CO₂
• 10,000 molecules H₂O = 1.66 × 10⁻²⁰ mol H₂O
• 8.75 x 10³² molecules C₆H₁₂O₆ = 1.45 × 10⁹ mol C₆H₁₂O₆
