WebA sample of gas has a volume of 12 liters at 0°C and 380 torr. What will be its volume when the pressure is changed to 760 torr at a constant temperature? ... A mixture of neon and oxygen gases, in a 9.77 L flask at 65 °C, contains 2.84 grams of neon and 7.67 grams of oxygen. The partial pressure of oxygen in the flask is ? WebDec 3, 2024 · Your first step is to calculate the volume of stock solution that is required. M dilution V dilution = M stock V stock. (1.0 M) (50 ml) = (2.0 M) (x ml) x = [ (1.0 M) (50 ml)]/2.0 M. x = 25 ml of stock solution. To make your solution, pour 25 ml of stock solution into a 50 ml volumetric flask. Dilute it with solvent to the 50 ml line.
