Step 1

000 \times 10^{5}$ L at STP (Standard Temperature and Pressure). At STP, one mole of any gas occupies 22.4 L. Therefore, the number of moles of methane can be calculated using the formula: \[ n = \frac{V}{V_{m}} \] where $ n $ is the number of moles, $ V $ is Show more…

Key Concepts

Molar Volume at STP

At standard temperature and pressure (STP), one mole of an ideal gas occupies a fixed volume. This known molar volume, typically 22.414 liters per mole, provides a straightforward way to convert the volume of a gas at STP into the number of moles present.

Mole Concept

The mole is a fundamental unit in chemistry that quantifies the amount of a substance. It connects the macroscopic scale (grams, liters, etc.) with the microscopic scale (particles, atoms, or molecules) and provides the basis for conversions and stoichiometric calculations.

Molar Mass

Molar mass is the mass of one mole of a substance, expressed in grams per mole. It allows for the conversion from moles to grams, and is determined by summing the atomic masses of all atoms in a molecule. This is crucial in quantifying the mass of a chemical species once the number of moles is known.
