$1.)$ Use the line of best fot to calculate the concentration of the salicylic Acid in your asprin saple solution$($in $50\mathrm{.}0$ mL volumettic flask$)$

$2.)$ Use M$1$V$1=$M$2$V$2$ to determine the concentration of salicylic acid in your $100\mathrm{.}0$ mL solution before dilutuon to $50\mathrm{.}0$mL for analysis.

$3.)$ Determine the mass of salicylic acid present in the ~$\mathrm{.}4$g sample of synthesized asprin tht was dissolved in the $100\mathrm{.}0$mL volumetric flask.

$4.)$ Determine the percent of salicylic acid and percent asprin in the ~$\mathrm{.}4$g sample of synthesized asprin?

$5.)$ Calculate the theoretical yeild of asprin for your synthesis reaction. Assume that the salicylic acid used in the salicylic used in the synthesis reaction is the limiting reactant.

$6.)$ Deterrmine the percent yild of the asprin for your synthesis.

For the $1$st caculation i got $1\mathrm{.}340$x$10^-4$ M C$7$H$603$

For the $2$nd calculation i got M$1=67$x$10^-5$

Please check my calculations and explain the remaining.
