A 25.0-liter gas cylinder contains 9.1 moles of nitrogen gas and \( 3.2 \) moles of oxygen gas. If the temperature of inside the cylinder is \( 0^{\circ} \mathrm{C} \), what is the total pressure inside the cylinder? Suppose that Daniel has a \( 2.00 \mathrm{~L} \) bottle that contains a mixture of \( \mathrm{O}_{2}, \mathrm{~N}_{2} \), and \( \mathrm{CO}_{2} \) under a total pressure of \( 5.10 \) atm. He knows that the mixture contains \( 0.290 \mathrm{~mol} \mathrm{~N}_{2} \) and that the partial pressure of \( \mathrm{CO}_{2} \) is \( 0.250 \) atm. If the temperature is \( 273 \mathrm{~K} \). what is the partial pressure of \( \mathrm{O}_{2} \) ?
