Question

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 70.2 mL and contains 33.4 g of argon.

part a:

Assuming ideal gas behavior, what is the pressure in the canister at 318 K ?

Express your answer with the appropriate units.

part b:

When the argon is released from the canister it expands to fill the wine bottle. How many 750.0-mL wine bottles can be purged with the argon in the canister at a pressure of 1.17 atm and a temperature of 318 K ?

Express your answer as an integer.
