A certain gasol occupies a volume of 12.5 L at 50 degree Celsius and 740 torr. what would its volume be at STP? do the equation using the formula PV=nRT

Respuesta :

n=PV/RT

convert:

740 torr to atm (1 atm=760 torr)

50 degree celsius to kelvin ( degree celsus +273= kelvin)

n=(0.9737 atm)(12.5L)÷(0.08206 L atm mol ⁻¹k⁻¹) (323 K)

n=0.4592 mols×22.4 L/1 mol.   (22.4 L STP= 1 mol)

=10.286 L at STP

it could be this
