7. (a) In solving pV = nRT for n , we first convert the temperature to the Kelvin scale: (40.0 273.15)K 313.15 K T =+ = . And we convert the volume to SI units: 1000 cm 3 = 1000 × 10 –6 m 3 . Now, according to the ideal gas law, () ( ) ( ) 56 3 2 1.01 10 Pa 1000 10 m 3.88 10 mol. 8.31J/mol K 313.15K pV n RT
