Here’s a table to help visualize the calculation: neon
|Number of moles (n)||2.00 mol|
|Molar volume at STP (V)||22.4 L/mol|
|Volume (V)||2.00 mol × 22.4 L/mol|
Therefore, 2.00 moles of neon gas will occupy a volume of 44.8 liters at STP.
We can use the molar volume of an ideal gas at STP, which is approximately 22.4 liters/mol, to calculate the volume that 2.00 moles of neon gas will occupy at STP.
Given that there are 2.00 moles of neon gas, we can use the following equation to determine the volume:
Volume is equal to the product of the number of moles and the molar volume.
Volume = 2.00 moles 22.4 mol/mol
= 44.8 liters in volume
Therefore, at STP, 2.00 moles of neon gas will take up 44.8 liters of space.
Neon Gas: Illuminating the Mysteries of an Elemental Gem
Neon, denoted by the symbol Ne and atomic number 10, stands as a captivating chemical element, existing as a colorless, odorless, and inert gas under standard conditions. As the second-lightest noble gas, succeeding helium, neon distinguishes itself with a mesmerizing reddish-orange glow when activated within a vacuum discharge tube.
Discovery Journey of Neon: A Serendipitous Encounter with Science
In 1898, British chemists Sir William Ramsay and Morris Travers unearthed neon’s presence as part of the most volatile fraction within liquefied crude argon derived from air. This revelation marked the culmination of extensive research into noble gases, a group defined by chemical stability and a lack of reactivity.
Neon’s Characteristics: A Harmonious Symphony of Inertness
Belonging to the noble gases, renowned for their inert nature due to filled outer electron shells, neon’s lack of reactivity positions it as a superb choice for diverse applications. Notably, it finds utility in fluorescent lamps and distinctive signage.
Applications of Neon: Brightening the Global Landscape
Foremost among neon’s applications is its role in crafting iconic neon signs, serving as vivid symbols of cities and businesses globally. When electrically stimulated within a vacuum discharge tube, neon emits its characteristic reddish-orange glow, contributing to the vibrant signage ubiquitous today.
Beyond signage, neon plays a crucial role in fluorescent lamps, creating the inert environment necessary for ultraviolet radiation to excite phosphor, producing visible light—a popular choice for energy-efficient lighting.
In various industries, neon shines through in applications such as:
- High-voltage indicators and switching gear: Neon’s glow proves invaluable in indicating high voltage in electrical equipment.
- Lightning arresters: Leveraging its inertness and voltage resilience, neon becomes an integral part of lightning arresters, safeguarding electrical systems from lightning strikes.
- Diving equipment: Neon is utilized in diving gas mixtures, offering a safer alternative to regular air, less prone to causing narcosis.
- Lasers: Neon contributes to specific laser types, where its properties aid in generating coherent light.
- Cryogenic refrigeration: Neon’s low boiling point positions it as a valuable refrigerant for applications demanding extremely low temperatures.
Neon’s Rarity and Eco-Footprint
With an Earthly abundance of merely 18.18 parts per million in the atmosphere, neon undergoes extraction through fractional distillation. While neon’s inert nature minimizes environmental impact, concerns arise about the sustainability of current extraction methods, considering the energy-intensive processes involved.
