The number of liters of a gas that would produced at STP is 121.86 Liters
calculation
Step 1 : calculate the moles of hydrogen chloride gas using ideal gas equation
That is PV=nRT where,
P( pressure) = 5100 mm hg
V(volume)= 20.1 L
n(number of moles)= ? moles
R( gas constant) = 62.3636 L.mmhg/mol.K
T( temperature) =29 °C in to kelvin = 29 +273 =302 K
by making n the subject of the formula by diving both side by RT
n= Pv/RT
n=[(5100 mm hg x20.1 L)/(62.3636 l.mmhg/mol.k x 302 K)] =5.44 moles
Step : calculate the liters of a gas at STP
that is at STP
1 moles = 22.4 L
5.44 moles=? L
by cross multiplication
=( 5.44 mole x 22.4 L) / 1 mole =121.86 liters
