The volume of ethane at STP has been 136,6 L. The volume of gas at 100[tex]\rm ^\circ C[/tex] has been 186,6 L.
STP has been the state of standard temperature and pressure. At STP, the temperature has been 273.15 K, while the pressure has been 1 atm.
Assuming ethane has been an ideal gas:
PV = nRT
P = pressure = 1 atm
V = volume
n = moles = 6.1
R = constant = 0.08206 atm.L/mol.K
T = temperature = 273.15 K
Substituting the values:
Volume = 6.1 mol × 0.08206 atm.L/mol.K × 273.15 K
Volume = 136,6 L.
The volume of ethane at STP has been 136,6 L.
Considering the temperature of the gas being 100[tex]\rm ^\circ C[/tex]:
Temperature = 373.15 K
Volume = 6.1 mol × 0.08206 atm.L/mol.K × 373.15 K
Volume = 186,6 L.
The volume of gas at 100[tex]\rm ^\circ C[/tex] has been 186,6 L.
