The moles of gas produced is 0.0742 moles
calculation
The moles of a gas is calculated using ideal gas equation
that is Pv=nRT
where, P(pressure)= 747 torr
V(volume) = 2L
n( number of moles)=?
R( gas constant) = 62.364 L.torr/mol .K
T( temperature)= 50°C into kelvin = 50 + 273 =323K
make n the subject of the formula by dividing both side of equation by RT
n= PV/RT
n=[ (747 torr x 2L) /( 62.364 L.torr/Mol.K x 323 K)] =0.0742 moles
