A solution containing a protein of unknown molecular mass

was analyzed using electrosprony time$-$of$-$flight $($TOF$)$ mass

spectrometry. The resalting mass spectrum contained $10$

$M{H}_n^{+}$peaks. The table displays the $\frac{m}{z}$ values of $7$ of those

$10$ peaks. Determine the charge $(n)$ of each of the $10$ peaks in

the mass spectrum. Round the values for the charges to the

nearest whole number.

peak I charge $(n)$ :

peak $2$ charge $($in$)$:

peak $3$ charge $(n)$ :

peak $4$ charge $($is$)$:

peak $5$ charge $(n)$ :

peak $6$ charge $($n$)$:

peak $7$ charge $(n)$ :

peak $8$ charge $($n$)$:

peak $9$ charge $(n)$ :

peak $10$ charge $($a$)$ :

Use peaks $2,3,4,6,7,9,$ and $10$ to determine the average

molecular mass $(M)$ of the neutral protein.
