[Tex/LaTex] Itemize spacing

Question

I don't use LaTeX that much, so I'm really clumsy with this stuff.

I've being searching for what I needed but since it appears there're no examples (or maybe I'm just bad at this) I decided to ask here.

I'm using some code that was giving to me in class, but I want to modify the way the itemize is looking.

\documentclass[final,letterpaper,twocolumn,authoryear,11pt]{elsarticle}
\usepackage{geometry}
\geometry{verbose,tmargin=2.5cm,bmargin=2.5cm,lmargin=2.5cm,rmargin=2.5cm}
\usepackage{enumitem}

\begin{document}
Donde,
\begin{itemize}  
\itemsep=0ex \itemindent=1cm 
\item[$K^B_A$:]  Constante de equilibrio químico, adim.
\item[$m_{A,liquid}$:] Concentración de A en la solución, mol/m\textsuperscript{3}.
\end{itemize}
\end{document}

I would like m_{A,liquid} to start just underneath K^B_A with the same spacing and, if it is possible, to make mol/m^3 move just underneath "Concentración".

Hope you could understand my question and help me!

Like this, with enumitem and enumerate?

\documentclass[final, letterpaper, twocolumn, authoryear, 11pt]{elsarticle}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{geometry}
\geometry{verbose,margin=2.5cm, showframe}
\usepackage{amsmath}
\usepackage{enumitem}

\begin{document}

Donde,
\begin{enumerate}[wide, itemsep=0pt, leftmargin =*,widest={$m_{A,\mathrm{liquid}}$}]
  \item[$K^B_A$:] Constante de equilibrio químico, adim.
  \item[$m_{A,\text{liquid}}$:] Concentración de A en la solución, mol/m\textsuperscript{3}.
\end{enumerate}

\end{document}
