The temperature in kelvin does 60.5 liters of sulfur dioxide occupy if there are 2.5 mole at 0.75 atm is 221.07 kelvin 
 Step-by-step explanation
 This is calculated using ideal gas equation, that is PV=nRT
where,  P(pressure) = 0.75 atm
 V(volume) = 60.5 L
 n(moles) = 2.5 mole
 R( gas constant) = 0.0821 L.atm/mol.k
 T(temperature =?
by making T the subject of the formula 
T is therefore =Pv/nR
T= (0.75 atm x 60.5 L) / ( 2.5 molex 0.0821 L.atm/mol.K) = 221.07 kelvins
