At what celsius temperature will it exert a pressure
A gas confined in a 519.1-mL container exerts a pressure of 107 mm Hg at 38.6 degrees Celsius. At what Celsius temperature will it exert a pressure of 635.7 mm Hg if it is placed into a 644 mL container?

A mixture of CH4 and H2O is passed over a nickel catalyst at 1000 K. The emerging gas is collected in a 5.00 L flask and is found to contain 8.62 g of CO, 2.60 g of H2, 43.0 g of CH4, and 48.4 g of H2O. Assuming that equilibrium has been reached,
A solution is made by dissolving 31.0 g of NaOH in approximately 450 mL of water in a volumetric flask. The solution becomes quite warm, but after it is allowed to return to room temperature, water is added to total 500 mL of solution.
