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: 

PV=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:
