A major component of gasoline is octane (C8H18) . When octane is burned in air, it chemically reacts with oxygen gas (O2) to produce carbon dioxide (CO2) and water (H2O).
What mass of octane is consumed by the reaction of 5.0g of oxygen gas?
To a 100 mL volumetric flask are added 1.00 mL volumes of three solutions: 0.0100 M AgNO3, 0.220 M NaBr, and 0.100 M NaCN. The mixture is diluted with deionized water to the mark and shaken vigorously.
From the same container under the same conditions--same temperature and initial pressure, it takes 385 s for 7.00 L of O2 gas to effuse. Calculate the molar mass (in grams/mol) of the unknown gas.
