Calculating the Final Pressure of a Gas Sample

Introduction

When dealing with gas laws, it is important to understand how different variables such as volume, pressure, and temperature are related to each other. In this scenario, we have a gas sample with initial conditions that changes as it is heated. We will use the ideal gas law to calculate the final pressure of the gas sample.

Given Data

A sample of gas has an initial volume of 3.50 L at a pressure of 970. torr and a temperature of 25°C. If the sample is heated to a temperature of 40°C and expands to a volume of 6.80 L, what is the final pressure in torr?

Answer:

Answer:

The answer for the volume is approximately 524.4L

Step by Step Explanation:

P1V1/T1=P2V2/T2

Where P1=970torr

T1=25°C=273+25=298K

V1=3.5L

P2=X

T2=40°C=273+40=313K

V2=6.8L

P2=P1V1T2/V2T1

X=970×3.5×313/6.8×298

X=524.395L

X≈524.4L

A sample of gas has an initial volume of 3.50 L at a pressure of 970. torr and a temperature of 25°C. If the sample is heated to a temperature of 40°C and expands to a volume of 6.80 L, what is the final pressure in torr? The final pressure of the gas sample is approximately 524.4 torr.
