Problem: A wine-dispensing system uses argon canisters to pressurize and preserve wine in the bottle. An argon canister for the system has a volume of 59.6 mL and contains 30.1 g of argon.Assuming ideal gas behavior, what is the pressure in the canister at 297 K ?

FREE Expert Solution

We are asked to find the pressure in the canister containing argon gas at the given conditions. Since mass, volume and temperature are given, we will use the ideal gas equation to calculate for pressure.

PV = nRT

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


We will do the following steps to solve the problem:

Step 1: Calculate the moles of argon gas in the canister

Step 2: Calculate the pressure in the canister


Step 1: Calculate the moles of argon gas in the canister

In the ideal gas equation, moles are needed but the mass of argon is given instead. We’ll calculate the moles of argon using the mass and its molar mass.
