The chemical equation for the combustion of ethane is
$2\mathrm{}{\mathrm{C}}_2{\mathrm{H}}_6+7{\mathrm{O}}_2\to 4\mathrm{}{\mathrm{C}\mathrm{O}}_2+6\mathrm{}{\mathrm{H}}_2\mathrm{O}$
$60\mathrm{}\mathrm{g}$ of ethane was completely burnt in oxygen. Answer the following question:

How would you test the presence of water as a product of this reaction?
