What Volume Will 185g of Butane Occupy at 745 Torr and 35 °C?

Gas volume calculations may seem like a complex web of scientific jargon, but they play a crucial role in various fields. From industrial applications to everyday scenarios, understanding the volume of gases, such as butane, under specific conditions is essential. In this article, we’ll unravel the mystery behind calculating the volume of 185g of butane at 745 Torr and 35 °C. So, buckle up as we dive into the molecular world of butane and explore the fascinating relationship between pressure, temperature, and volume.

Butane: A Molecular Perspective

Before delving into calculations, let’s take a moment to understand butane from a molecular standpoint. Butane is a hydrocarbon with a linear molecular structure, consisting of four carbon atoms and ten hydrogen atoms. This composition plays a significant role in how butane behaves under different conditions.

Pressure, Temperature, and Volume Relationship

Gas laws, including Boyle’s Law and Charles’s Law, govern the behavior of gases like butane. Boyle’s Law states that the pressure and volume of a gas are inversely proportional at constant temperature, while Charles’s Law relates volume and temperature at constant pressure. The Combined Gas Law merges these two, providing a comprehensive understanding of the pressure, temperature, and volume relationship.

Initial Conditions: 185g of Butane at 745 Torr and 35 °C

Our starting point involves 185g of butane held at 745 Torr and 35 °C. To ensure accurate calculations, it’s crucial to convert these units into a standardized system, setting the stage for applying the Ideal Gas Law.

Ideal Gas Law and its Application

The Ideal Gas Law, expressed as PV = nRT, combines pressure, volume, temperature, and the gas constant. Applying this law allows us to determine the volume of butane under the specified conditions.
