\documentclass[11pt]{article}  
\usepackage{siunitx}
\usepackage{amsmath}

\begin{document}
\begin{align*}
\text{Concentration of unknown sample solution} &= \frac{303 - 0.00227}{0.215} \\
&= 1.400 \si{\mg \per \L}
\end{align*}
\end{document}

Is it possible to have a line break like this?

concentration of unknown =
    sample solution

And increase the spacing between the equations?

    It should be \SI{1.400}{\mg\per\L} – egreg Nov 10 '14 at 23:29
  • @egreg So that's why my units were touching the numbers. I thought it was meant to be like that. – Jack Nov 10 '14 at 23:39

    A thin space should separate the number from the unit, which is what \SI does. – egreg Nov 10 '14 at 23:40

\documentclass[11pt]{article}  
\usepackage{siunitx}
\usepackage{amsmath}

\begin{document}
\begin{align*}
\parbox{5cm}{\centering Concentration of unknown sample solution} 
&= \frac{303 - 0.00227}{0.215} \\[\jot]
&= \SI{1.400}{\mg \per \L}
\end{align*}
\end{document}  
  • varwidth or tabular instead of \parbox? – egreg Nov 10 '14 at 23:33
