Gaseous ethane

CH3CH3

will react with gaseous oxygen

O2

to produce gaseous carbon dioxide

CO2

and gaseous water

H2O

. Suppose 19. g of ethane is mixed with 97.2 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.

Please can you solve this problem using the EXACT mass numbers of the elements from ALEKS and NOT the ones in the periodic table? Thanks
