Exercise 5

Some air at a pressure of 3 bar and at a temperature of $60 ^ { \circ } \mathrm { C }$ occupies a volume of
$0.08 \mathrm {~m} ^ { 3 }$ . Calculate the mass of the air, correct to the nearest gram, assuming the characteristic
gas constant for air is $287 \mathrm {~J} / ( \mathrm { kg } \mathrm { K } )$ .
