Nitrous oxide, also known as laughing gas, is commonly used in hospitals to alleviate pain. The gas is stored inside 25L steel canisters under high pressure. When delivered to the hospital, the canisters warm up to 28oC. What is the pressure inside a new canister if there are 50 moles of gas? The ideal gas constant is 8.314 L⋅kPa⋅K−1⋅mol−1.
