The Ideal Gas Law Video Lessons

Concept: Boyle's Law

# Problem: In a 1 L container, 0.750 L of argon at 1.50 atm and 177°C is added with 0.235 L of sulfur dioxide at 95.0 kPa and 63.0°C. If the temperature is then at 25°C, what is the pressure?A. 0.167 atm B. 0.946 atm C. 0.681 atm D. 0.524 atm E. 0.199 atm

###### FREE Expert Solution

We are asked to calculate the pressure in the container:

We are going to use the ideal gas law for this problem:

$\overline{){\mathbf{PV}}{\mathbf{=}}{\mathbf{nRT}}}$

P = pressure, atm
V = volume, L
n = moles, mol
R = gas constant = 0.08206 (L·atm)/(mol·K)
T = temperature, K

We go through the following steps to solve this problem:
