A major component of gasoline is octane  C8H18 . When liquid octane is burned in air it reacts with oxygen  O2  gas to produce carbon dioxide gas and water vapor. Calculate the moles of oxygen needed to produce  0.600mol  of carbon dioxide. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Aqueous hydrobromic acid (HBr) will react with solid sodium hydroxide (NaOH) to produce aqueous sodium bromide (NaBr) and liquid water (H,0). Suppose 18. g of hydrobromic acid is mixed with 17.3 g of sodium hydroxide. Calculate the minimum mass of hydrobromic acid that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits.
