[Tex/LaTex] Is it possible to use the width of one TikZ node to calculate the width of another

Question

Is it possible to store the variable width of a node and use that width to calculate the text width of another node in TikZ?

Example

I have a list of similar nodes side-by-side (inline, not overlaid). Let's call the left column of nodes "A" and the right column of nodes "B". Column A nodes contain a number (counter variable, which means the node gets wider at each digit carry-over). Column B nodes should have some text width minus the text width of the corresponding node in column A.

get width of node A = \fontsize{50}{60}\selectfont\countervalue{}
text width of node B = (\textwidth) – (width of node A)

I think the answer I am looking for is hidden somewhere in this answer.

Did I understand correctly?

\documentclass[border=5mm,tikz]{standalone}
\usetikzlibrary{calc}
\usepackage{lipsum}
\begin{document}

\begin{tikzpicture}
\foreach\j in {1,10,100}{
\node[outer sep=0] (a-\j) at (0,{-7*log10(\j)}) {\j};
\path let \p1=($(a-\j.east)-(a-\j.west)$) 
  in 
  node[anchor=west,text width=\textwidth-\x1] (b-\j) at (a-\j.east) 
    {\lipsum[1]};
}
\end{tikzpicture}

You need to pass the expression through a math parser first in order to evaluate it. One way of doing this is to use \pgfmathparse{<expression>}, and then printing the result using \pgfmathprintnumber[<optional number formatting keys>]{\pgfmathresult}:

\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{calc}
\usepackage{siunitx}
\begin{document} 
\begin{tikzpicture}
\draw[step=0.1cm,black!10,very thin] (-0.1,-0.1) grid (10.2,10.2);%setting up grid and axes
\draw[step=1cm,black!50,help lines] (-0.1,-0.1) grid (10.2,10.2);
\draw[thick,->] (0,0) -- (10.2,0);
\draw[thick, ->] (0,0) -- (0,10.2);
\foreach \x in  {0,1,...,10}
\draw[thick] (\x,-2pt) -- (\x,2pt);%drawing tick marks

\foreach \x in {0,2,...,10}
\draw node at (\x, -10pt) {%
    \pgfmathparse{0.1*\x}% Evaluate the expression
    \pgfmathprintnumber[    % Print the result
        fixed,
        fixed zerofill,
        precision=1
    ]{\pgfmathresult}%
};
\foreach \y in {1,3,...,9}
\draw node at (-15pt,\y) {%
    \pgfmathparse{2.5*\y+272.5}%
    \pgfmathprintnumber{\pgfmathresult}%
};
\draw node at (9,-25pt) {Mole Fraction $\chi_{NB}$};
\draw node at (-40pt, 5)[rotate=90]{Temperature[$\si{\celsius}$]};
\draw node at (5,3.2){2 Phases};
\draw node at (1,6.2)[rotate=0]{1 Phase};
\draw node at (9,7.2)[]{1 Phase};
\foreach \y in {0,1,...,10}
\draw[thick](-2pt,\y) -- (2pt,\y);
\draw[very thick] plot[smooth] coordinates{(0.5,0) (2,5)(4,8) (6,9)(7,8.5)(8.5,5)(9,0) };
\end{tikzpicture}
\end{document}
