Julianne Alexander · Answer 1

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
