Please see the work below.

Work Step by Step

We know that a. The balanced chemical equation for the thermal decomposition of ammonium nitrate can be given as $NH_4NO_3\rightarrow NO_2+2H_2O$ b. We know that $PV=nRT$ This can be rearranged as: $R=\frac{PV}{nT}$ We plug in the known values to obtain: $R=\frac{0.9947\times 0.340}{0.0128\times 297}=0.08251\frac{L.atm}{mol.K}$
