I assume you're referring to the mole ratio that exists between the atoms that form the molecule.

Here's how the TEA molecule looks like

TEA is basically a tertiary amine that has three alcohol groups attached. Its empirical formula, which is also its molecular formula, is ${C}_{6} {H}_{15} {O}_{3} N$.

The subscripts each element has represent the number of moles of that respective element needed to make 1 mole of TEA. In other words, 1 mole of TEA has

• 6 moles of carbon;
• 15 moles of hydrogen;
• 3 moles of oxygen;
• 1 mole of nitrogen;

So, the mole ratios that exist between the elements that make up TEA are

$\text{C"" : ""H"" : ""O"" : ""N" = 6" : "15" : "3" : } 1$
