The molecule of  mixture  cannot be seen hence, it will be considered as homogeneous mixture.

<h3>What is molecule?</h3>

A molecule is just a collection of more than two atoms bound together by chemical bonds; depending on the context, the phrase doesn't have to include ions that meet this requirement.

<h3>What is homogeneous mixture?</h3>

Solids, liquids, as well as gases, can all be homogeneous mixtures. Through, they have almost the same look and chemical makeup.

When sugar will be dissolved, the sucrose molecules get separated from one another. The materials that make up individual molecules stay together like sucrose molecules sucrose molecules, so the molecule will not break up.

Therefore mixture can be considered as molecule and homogeneous mixture.

Mila [183]

First of all water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms. So lets say x = 3m, m=1, and x=3, because 3 x 1 = 3 = x, and r = radius of drinking fountain's water dispense, and AOW = amount of water produced in a minute, and y = (x*(r*(AOW/r))... So Y = a, and a = answer... Meaning your answer is (y = (x*(r*(AOW/r)) )!
