1. What is Heptane?

Heptane (C₇H₁₆) is a straight-chain alkane with seven carbon atoms. It's a colorless liquid hydrocarbon that is a component of gasoline and used as a solvent in laboratories.

2. How Does the Calculator Work?

The calculator uses the molar mass of heptane (100.21 g/mol) to convert between mass and moles/molecules:

\[ \text{Moles} = \frac{\text{Mass (g)}}{\text{Molar Mass (g/mol)}} \] \[ \text{Molecules} = \text{Moles} \times 6.022 \times 10^{23} \]

Where:

Molar mass of heptane = 100.21 g/mol
Avogadro's number = 6.022 × 10²³ molecules/mol

3. Importance of Molar Mass

Details: Molar mass is fundamental in chemistry for converting between mass and number of particles. It's essential for stoichiometric calculations in chemical reactions.

4. Using the Calculator

Tips: Enter the mass of heptane in grams and select whether you want to convert to moles or molecules. The calculator will perform the conversion using the exact molar mass of heptane.

5. Frequently Asked Questions (FAQ)

Q1: What is the molecular formula of heptane?
A: The molecular formula is C₇H₁₆, meaning it contains 7 carbon atoms and 16 hydrogen atoms.

Q2: Why is the molar mass 100.21 g/mol?
