Expert Answer

Step 1

Here, we have to calculate mass of ethane that is left after the reaction.

Step 2

Given:

    Mass of ethane = 2.1 g.

    Molar mass of ethane = 30 g/mol.

    Mass of oxygen = 11.5 g.

    Molar mass of oxygen = 32 g.

    Molar mass of carbon dioxide = 44 g.

Step 3

Balanced chemical reaction between e...
