\label{eq:mu}
\mu=\gamma\hbar\sqrt{I(I+1)}
\end{equation}
where \gamma is the known gyromagnetic constant for protons and
calculating I is the nuclear spin quantum number. We could calculate $N$ for 125 mL of water, the volume that was used in this experiment.
\subsection{Studying Larmor Precession}
We examined the relationship between precession frequency and magnetic field as discussed in the Methods section. we can see by Eq.~\ref{eq:precession} that precession frequency should vary linearly with magnetic field, which is what we see in Fig.~\ref{fig:precession}. The slope of the line is the gyromagnetic constant, and the intercept represents the frequency without any extra applied field.
