Gaseous ethane (CH 3 CH 3 ) will react with gaseous oxygen (O 2 ) produce gaseous carbon dioxide (CO 2 ) and gaseous water (H 2 O) . Suppose 0.90 g of ethane is mixed with 6.69 g of oxygen. Calculate the minimum mass of ethane that could be left over by the chemical reaction. Be sure your answer has the correct number of significant digits.
