Earth's atmosphere is a <em>mixture</em> of gases that have
not reacted to become chemical compounds.
As the density of the unknown substance is 0.68g/0.8ml = 0.85g/ml, it is less dense than the maple syrup at 1.33g/ml and will float.

<em>Hence, </em><em>Clark</em><em> a greater change in position than Dora.</em>
