Sorry I won't be doing the calculations but I will give you the formula. PV=nRT Here P(pressure):101.3kPa=1.013*10^5 Pa V(volume):We have to find it T(Temperature):25C=25+273=298 K (Si unit of temperature is kelvin) n(number of moles):1 (Molar means one mole) R(gas constant)=8.314 Put the values and do the calculations and find V. Similarly find out for 110 kPa

Sorry I won't be doing the calculations but I will give you the formula. PV=nRT Here P(pressure):110kPa=1.1*10^5 Pa V(volume):We have to find it T(Temperature):-78C=-78+273=195 K (Si unit of temperature is kelvin) n(number of moles):1 (Molar means one mole) R(gas constant)=8.314 Put the values and do the calculations and find V. Similarly find out for 101.3 kPa
