See the answer below.

Work Step by Step

a) From Dalton's law and the stoichiometry: $P_{N_2}=6/(6+1+12+10)×4.2\ atm=0.87\ atm$ b) From ideal gas law: $PV=nRT$ $n=4.2\ atm×1.5\ L/0.082057\ atm.L/mol.K\div (450+273)\ K$ $n=0.106\ mol$ From stoichiometry: $0.106\ mol×4/(6+1+12+10)=$ $0.0146\ mol$ of nitroglycerin $0.0146\ mol×227.09\ g/mol=3.31\ g$
